Question

Find “h” if r=5 and V=100π

Answer 1

4

Explanation:

The equation for the volume of a cylinder is
`V=\pi r^(2) h`. So if V is 100
`\pi`, it means that
`\pi hr^(2)` is
`100\pi`. So the you plug in the information you know
`25h\pi =100\pi`. The pi cancels out and you end up with
`25h=100` meaning that h=4

Answer 2

Explanation:

V = π.
`r^(2)`.h

100π = π.
`(5)^(2)`.h

h = 4
