Question

Volume of cone if height is 18 and diameter is 10,

Answer 1

150pi

Explanation:

The formula for the volume of a cone is one-third the volume of a cylinder.

It is
`V=(1)/(3) Bh` where B is the area of the circle base and h is the height of the cone.

To find the base of the cone, use the formula for the area of a circle. So, the radius is 5. So, the area of the base is pi × radius².

`5^(2) =25`

`(1)/(3)` × 25pi × 18 = 150pi
