What is the radius of a cylinder that has a volume of 500ft cubed and that is 10 ft tall?

r =4 ft

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h

We know the volume and the height, and approximate pi by 3.14

500 = 3.14 r^2 *10

500 = 31.4 r^2

Divide each side by 3.14

500/31.4 = 31.4 r^2/31.4

15.2356688 = r^2

Take the square root of each side

sqrt(15.2356688) = sqrt(r^2)

3.99 = r

Rounding

r =4 ft

if x = 1, then the answer is 3.5

correct me if i'm wrong and if it is i'm truly sorry.
