A cylinder has a height of 14 feet. Its volume is 12,704.44 cubic feet. What is the radius of the cylinder?
Alenkinab [10]
<h3 /><h3>V. Cylinder =  π . r² . h</h3>

12,704.44 = 3.14 × r² × 14

12,704.44 = 3.14 × 14 × r²

12,704.44 = 43.96 × r²

r² = 12,704.44/43.96

r² = 289

r = √289

r = 17

Helllohello help please if you want -
zaharov [31]

Answer:

True

Step-by-step explanation:

Let's take a problem such as 3x-2=6

To isolate the variable, you must get rid of everything on one side and essentially do the inverse to the other side. We see -2, so you have to add 2 to each side.

Now you have 3x=8

Next, we device each side by 3. Right now, x is being multiplied by 3 so we have to do the inverse.

Answer is x = 8/3 or 2.666666666666667
