Formula

volume = (1 / 3) x pi x radius^2 x height

The formula uses the circular base area and scales it by the height and one-third factor.

Make sure the height is measured straight down, not along the slanted side.

Example

Radius 3 and height 5 gives volume about 47. 12

Check

Using slant height instead of vertical height
Forgetting the one-third factor in the formula
