Question

What is the volume of the cone

Answer 1

12.56 cubic units

Explanation:

Let h be the height of given cone.

`h = \sqrt{ {5}^(2) - {4}^(2) } \\ = √(25 - 16) \\ = √(9) \\ = 3 \\ \\ volume \: of \: cone \\ = (1)/(3) \pi {r}^(2) h \\ \\ = (1)/(3) * 3.14 * {2}^(2) * 3 \\ \\ = (1)/(3) * 3.14 * 4 * 3 \\ \\ =3.14 * 4 \\ = 12.56 \: {units}^(3) \\`
