Problem 7 (a)

Pick any two values you want for the radius and height (r and h). Repeats are allowed.

I'll go with r = 1 and h = 1

Compute the surface area of the cylinder with these parameters.

SA = 2pi*r^2 + 2*pi*r*h

SA = 2pi*1^2 + 2pi*1*1

SA = 2pi + 2pi

SA = 4pi

Now double the radius. We go from r = 1 to r = 2. Keep the height the same and compute the new surface area.

SA = 2pi*r^2 + 2*pi*r*h

SA = 2pi*2^2 + 2*pi*2*1

SA = 8pi + 4pi

SA = 12pi

The jump from 4pi to 12pi is "times 3".

Answer: The surface area triples

========================================================

Problem 7 (b)

Let's go back to r = 1 and h = 1 again.

LSA = lateral surface area of the cylinder

LSA = 2*pi*r*h

LSA = 2*pi*1*1

LSA = 2pi

Now double r, but keep h the same

LSA = 2*pi*r*h

LSA = 2*pi*2*1

LSA = 4pi

Going from 2pi to 4pi is a jump of "times 2"

Answer: The lateral area doubles

========================================================

Problem 7 (c)

We'll go back to r = 1 and h = 1.

Compute the volume of this cylinder.

V = pi*r^2*h

V = pi*1^2*1

V = pi

Then compute the volume with double the radius, but the same height

V = pi*r^2*h

V = pi*2^2*1

V = 4pi

The volume has quadrupled since we have gone from pi to 4pi.

Answer: Volume quadruples

========================================================

Problem 8

The volume of the block, before the half cylinders are removed, is 10*3*8 = 240 cubic inches.

The two half cylinders removed can be rearranged to combine to a full cylinder. This empty space cylinder has a radius of 8/2 = 4 inches and height 3 inches. This means we'll be kicking out the volume of pi*r^2*h = pi*4^2*3 = 48pi cubic inches of empty space.

The resulting volume of this weird looking solid is 240-48pi cubic inches.

--------------

The front panel is a 3 in by 10 in rectangle. It has area of 3*10 = 30 square inches. The same goes for the back wall.

The top or ceiling panel is going to involve us first finding the area of the 8 by 10 rectangle (if you didn't remove those circular portions). So we have 8*10 = 80 square inches to start with. Then we kick out the circle of radius 4. So the top and bottom panels have area of 80 - 16pi square inches each.

The left and right curved walls are the lateral sides of a full cylinder of radius 4 inches and height 3 inches. This is when we combine the two curved sides to form one cylinder.

LSA = 2*pi*r*h = 2*pi*4*3 = 24pi

This means each curved wall is 24pi/2 = 12pi square inches in surface area

Now add up the 6 sides mentioned

(front)+(back)+(top)+(bottom)+(left)+(right)

(30)+(30)+(80 - 16pi)+(80 - 16pi)+(12pi)+(12pi)

220-8pi

Which graph correctly represents the relationship between arc length and the measure of the corresponding central angle on a circle with radius r?

Answers

Any smooth curve connecting two points is called an arc. The correct option is c.

What is the Length of an Arc?

Any smooth curve connecting two points is called an arc. The arc length is the measurement of how long an arc is. The length of an arc is given by the formula,

[tex]\rm{ Length\ of\ an\ Arc = 2\times \pi \times(radius)\times\dfrac{\theta}{360} = 2\pi r \times \dfrac{\theta}{2\pi}[/tex]

where

θ is the angle, that arc creates at the centre of the circle in degree.

If the central angle has a measure of π/2(90°), then the length of the arc will be one-fourth of the total, while if the measure of the angle is π(180°), then the length of the arc will be half of the total.

Similarly, if the measure of the angle is 3π/4, then the length of the arc will be three-fourth of the total, while if the measure of the angle is (360°), then the length of the arc will be 2πr.

Hence, the correct option is c.

I am stuck on this one lol. Coleman pays $12.99 for 3 hamburgers. How much would Coleman pay for 10 hamburgers? Enter your answer in the box.

Answers

Answer:

$43.30

Step-by-step explanation:

What we know,

3 hamburgers = $12.99

Coleman wants to know how much would he have to pay for 10 hamburgers,

In order to find out how much 10 hamburgers cost, you need to find out how much 1 hamburger costs,

To find how much 1 hamburger costs divide 12.99 by 3,

12.99/3

= 4.33

Now we know that 1 hamburger cost $4.33,

Now time to find out how much 10 hamburgers cost,

Multiply 4.33 by 10,

4.33 × 10

= 43.30

Therefore it cost $43.30 for 10 hamburgers.

The length which result in a ratio closest to the golden ratio is equal to  7.5 inches and 4.5 inches. Option C is correct.

What is the length of line segment?

The line segment is made with two end points. Length of a line segment is the distance of both the ends of it.

A 12 inch line segment is divided into two parts. Suppose the line segment is AC which is divided into AB and BC parts. Thus,

AB+BC=AC

AB+BC=12                   ....1

The value of golden ratio is equal to 1.618. It can also be given as (1+√5)/2. The ratio of both segment is equal to golden ratio. Thus

[tex]\dfrac{AB}{BC}=\dfrac{AC}{AB}=\dfrac{1+\sqrt{5}}{2}\\\dfrac{12}{AB}=1.618\\AB=7.4166 \rm\; in[/tex]

Put this value in equation one as,

Answers

Based on the calculations, the total distance of Mara's run is equal to: C. 12 km.

How to determine the total distance of Mara's run.

In order to determine the total distance of Mara's run, we would solve for the length of the hypotenuse by applying Pythagorean's theorem and then add it to the other distances.

Mathematically, Pythagorean's theorem is given by this formula:

c² = a² + b²

Where:

c is the hypotenuse.a is the adjacent side.b is the opposite side.

Substituting the given parameters into the formula, we have;

c² = 3² + 4²

c² = 9 + 16

c = √25

c = 5 km.

Now, we can determine the total distance of Mara's run:

Total distance = 3 + 4 + 5

Total distance = 12 km.

Find the measures of angles Q and S. Number 7!

Answers

Step-by-step explanation:

by the way, you are completely and exactly right at 6.

Q is the inscribed angle of the (inner) arc angle TR.

and as such it is half of that arc angle TR.

S is now on the same side of the circle center as the segment TR. so, we have to flip the situation around :

S is half of the outside arc angle between T and R.

as the sum of the inner and outside arc angles are 360° (the full circle), the sum of half of their values is then

360/2 = 180°

so, yes,

x + 2 + 9x - 7 = 180

10x - 5 = 180

10x = 185

x = 18.5

Q = x + 2 = 18.5 + 2 = 20.5°

S = 9x - 7 = 9×18.5 - 7 = 166.5 - 7 = 159.5°

Answers

Answer:

h((4-x)(4-x) + k

h([tex]x^{2}[/tex]-8x+16)+k

if h = 2 , then

2[tex]x^{2}[/tex]-16x+32 + k

and we want 26  instead of 32 so subtract 6 so K = (-6)

What is Volume?

Volume can also be defined as the amount of space occupied by a 3-dimensional object. The volume of a solid like a cube or a cuboid is measured by counting the number of unit cubes it contains.

Volume will be,

V= Volume of rectangular pyramid + Volume of cuboid

 

Volume of rectangular pyramid= [tex]\frac{1}{3}[/tex] * base area* height

                                                   = [tex]\frac{1}{3}[/tex] * 6*8*(10-4)

                                                   =[tex]\frac{1}{3}[/tex] * 6*8*6

Volume of cuboid= l*b*h

                              = 4*6*8

So, Volume   =[tex]\frac{1}{3}[/tex] * 6*8*6 + 4*6*8

                     = [tex]\frac{1}{3}[/tex] (8)(6)(6)+(8)(6)(4)

How to determine the probability of winning?

From the question, we have the following parameters:

Number of a pair of numbers = 3

A die has 6 possible outcomes.

So, the probability of getting the first pair is:

P1 = 1/6

The probability of getting the second pair is:

P2 = 1/6

The probability of getting the first and the second pairs is

P = 1/6 * 1/6

Evaluate

P = 1/36

There are three pairs of numbers in total.

So, the probability of winning is:
