A circle has a diameter with endpoints at (0, 4) and (0, –8). What is the approximate area of the circle?

Answers

Answer 1

Answer:

113.04

Step-by-step explanation:

Area of a circle is πr2

π = 3.14

r = 6

πr2 = 113.04

Answer 2

Answer:

[tex]36\pi[/tex]

Step-by-step explanation:

The diameter is:

The Euclidean distance between points (x1, y1) and (x2, y2) is:

sqrt((x1 - x2)^2 + (y1 - y2)^2)

Substitute (x1, y1) = (0, 4) and (x2, y2) = (0, -8):

= sqrt((-0 + 0)^2 + (-(-8) + 4)^2)

= sqrt(12^2)

 = 12

or simply:

diameter: 4-(-8)=12

The radius is:

12/2=6 units

The area of the circle:

[tex]\pi r^2=\pi(6^2)=36\pi[/tex]

3. The sum of two numbers is 30 and their difference is 12. Find the two numbers.

Answers

Answer:

I don't know is it 12 and 16 I'm not sure

Answer:

The two numbers are 21 and 9

Step-by-step explanation:

Let the two numbers be a and b

The sum of these numbers is 30

a+b=30

The difference between these numbers is 12

a−b=12

                             ―――――――――

I.  You can solve this by logic.

If the two numbers were exactly equal, then they would both be 15.

15+15=30

But the difference would be 0, not 12

So if you lowered b by one point, and added that to a, then the two numbers would be 16 and 14, and the difference would be 2.

So you can see that for every point you subtract from b to add to a, you increase the distance between them by 2

So, by logic, you need to subtract 6 points from b and add them to a to create a difference of 12

(15+6) minus (15−6) gives a difference of 12

.m21.....−mm∩9       =  12

Answer:

The two numbers are 21 and 9

                   ―――――――――

II.  You can solve this by math

These are simultaneous equations, so you can solve them by math.

.a+b=30

.a−b=12

2a +0=42

What is the slope of the line shown in the graph?

A. -3/2
B. -1/2
C. 3/2

Answers

Answer:

-3/2

Step-by-step explanation:

Answer:

The slope of the line shown is -3/2.

Step-by-step explanation:

You can find this by using the rise/run method between the two points.

Between the two points, the line falls 3 units down (this is the rise part) and goes 2 units to the right (this is the run part). Since the line falls 3 units down between the two points, this number would be -3, and since it runs to the right by two units, the slope can be identified as -3/2.

yes

Step-by-step explanation:

I think you mean

"Is the product of 3/6 × 5/4 equal to the product of 3/4 × 5/6?"

If we can turn 3/6 * 5/4 into 3/4 * 5/6 using only legal math steps, then the answer is yes.

3/6 * 5/4 =

Breakup each fraction into a product of fractions.

= 3/1 * 1/6 * 5/1 * 1/4

Use the associative and commutative properties of multiplication to change the order and grouping of the multiplication.

= (3/1 * 1/4) * (5/1 * 1/6)

Do each product in parentheses.

= 3/4 * 5/6

This shows that 3/6 * 5/4 = 3/4 * 5/6
