the answer is 32 cubic feet

Answer:The radius is 32 cubic feet

Step-by-step explanation:The formula to find the volume of a cylinder is V=Bh or V=πr2h. So you would need to work backwards because you already have the volume and height.

3,818.24= 3.14r2*19

3,818.24= 3.14r*38

Because of the associative property, you can multiply 3.14 by 38

which is 119.32

So the next expression would be

3,818.24= 119.32r

How do you reverse multiplication? You need to divide both sides. In this case, you need to divide 3,818.24 by 119.32.

To get 32=r
