Volume of a cone formula: V = [tex]\pi r^{2} \frac{h}{3}[/tex]
where,
h is the height 9 in (assuming)
r is the radius want
v is the volume 602.88 cubic inches
[tex]\pi[/tex] is a = 3.14
Plug in everything:
[tex]602.88 = 3.14r^{2} (\frac{9}{3} )\\602.88 = 3.14r^{2} (3)\\1808.64 = 28.26r^{2}\\\frac{1808.64}{28.26} = \frac{28.26r^{2}}{28.26} \\r^{2} = 64\\r = \sqrt{64} \\r = 8\\or\\r =-8[/tex]
A copper pipe has an outside radius of 3 centimeters. The pipe is 200 centimeters long and the copper is 0.2 centimeters thick, so there is a cylindrical hole through the center of the pipe. What is the volume of the copper used to make the pipe
The volume of the copper used to make the pipe is 25.12 cm³.
To calculate the volume of the copper used to make the pipe, we use the formula below.
Formula:
V = πht²................ Equation 1Where:
V = Volume of the copperh = Length of the copper pipet = Thickness of the copper pipeπ = PieFrom the question,
Given:
h = 200 cmt = 0.2 cmπ = 3.14Substitute these values into equation 1
V = 200(3.14)(0.2²)V = 25.12 cm³Hence, the volume of the copper used to make the pipe is 25.12 cm³

An equilateral triangle has an apothem measuring 2.16 cm and a perimeter of 22.45 cm. What is the area of the equilateral triangle, rounded to the nearest tenth?
What is a triangle?A triangle is simply a two-dimensional polygon with 3 sides and 3 interior angles.
An equilateral triangle is a triangle with all its three sides having the same length
The area of an equilateral triangle is expressed as;
A = ((√3)/4)a²
Where a is the length of the side
Perimeter of an equilateral triangle is expressed as;
P = 3a
Where a is the length of the side
Given that the perimeter of the equilateral triangle is 22.45 cm, the sides of the triangle will be;
P = 3a
22.45cm = 3a
a = 22.45cm / 3
a = 7.48cm
Now, the area of the equilateral triangle will be;
A = ((√3)/4)a²
A = ((√3)/4) × (7.48cm)²
A = 0.433 × 55.9504cm²
A = 24.2cm²
The area of the equilateral triangle with the given perimeter is 24.2cm².
Hence, option D)24.2cm² is the correct answer.

Answer:
Circle
Step-by-step explanation:
because a hyper bole is (y-k) 2b2 -(x-h) 2a2=1
ellipse is = (x-h) 2a2 + (y-k) 2b2 = 1
parabola is y= a (x-h) 2+ k

The sum of three times Annabell's age plus her mother's age is 42. He
mother is 6 more than 6 times Annabell's age. How old is Annabell?
Answer:
4
Step-by-step explanation:
First you have to analyze the word equations. Let x equal to Annabell's age and y equal her mother's age
3x + y = 42
6 + 6x = y
Then you use substitution to find x
3x + 6 + 6x = 42
9x = 36
x = 4
What is radius? Help me out.
Answer:
Radius is half the diamiter of a circle, basically the whole length from one point of the circle to the middle.
Answer:
Radius is how far the middle of the circle is from the edge of the circle. For example, we know that a circle has a middle point and we know that we have a line around it in the shape of a circle. The radius would be the distance from the middle point to the outer line of the circle.
Find the missing angles.
Answer:
1: 81 is the overall angle, so to find the 2nd angle that makes up the overall angle, just subtract the 1st angle from the overall angle. it would be 81 - 44 = 37. so your answer is 37°.
2: this one is solved the same as number 1, just different numbers. it would be 98 - 59 = 39. your answer is 39°.
3. we know this is angle is a right angle because of the square indicating it. a right angle is 90°, so we would take 90 - 63 = 27. so your answer is 27°.

A line plot with Kelly's lengths of ribbons is shown
What is the total length, in inches, for all pieces of ribbon?
Answer: (I changed it back to fraction form instead of decimal because it seems that is how you are doing it)
Two possible lengths of ribbon (In inches) are 25 and 133 3/4
Step-by-step explanation
Okay, so- First, You need to find out how much ribbon is there before the two additional ones are added. Like this:
12 + 14 2/4 + 14 3/4 = 41 1/4
Next, subtract that amount from 200 to get the number of inches of ribbon that are needed to get 200 inches of ribbon. Like this:
(I changed it to a decimal to make it easier, so don't mind that)
200 - 41.25 = 158.75
So, 158.75 inches of ribbon are needed to get 200 inches. You can subtract any number less than 158.75 from that to get two seperate ribbon measurements.
(This might sound confusing so here)
For example:
158.75 - 25 = 133.75 (The bolded numbers are the two measurements)
158.75 - 65 = 93.75
So, Two possible lengths (in inches) of ribbon that kelly could have added are "25" and "133.75 "
Two possible lengths (in inches) of ribbon that kelly could have added are also "65" and "93.75"

(L.P)
z = 142°
y = 32° (alternative angle of angle FCA)
x = 142° (alternative angle of angle z)
2.x + 65 = 180
(l.p)
x = 180 - 65
x = 115°
y = x (alternative angle of x)
y = 115°
z = y (V.O.A)
z = 115°
~Tulpe⚘
Answer:
Step-by-step explanation:
2) Linear pair: Two angles are called linear when they are adjacent angles and the non common arms form a straight line. They add uo to 180
z + 32 = 180 {linear pair}
z = 180 - 32
z = 148°When parellel lines are cut by a transversal alternate interior angles are equal.
y = 32° {Alternate interior angles}
x = z {Alternate interior anlges}
x = 148°
3) x +65 = 180 {linear pair}
x = 180 - 65
x = 115°y = x {Alternate interior angles}
y = 115°z = y {Verically opposite angles}
z = 115°

The world health organization has studied the consumption of junk food in countries around the world since 2000. the function c = 179( 1.029 )^t models the amount of sods consumed in the world, where c is the amount consumed in billions of liters and t is the number of years since 2000.
approximately how much soda was being consumed when the study began in 2000?
Answer:
179 billion liters
Step-by-step explanation:
The variable t represents years since 2000, so in the year 2000 the value of t is zero.
When t=0, the exponential term is 1, so the value of the function is the multiplier of the exponential factor, 179.
