Question

What is the volume of this right cone?

• 27π cm³
• 200π cm³
• 213π cm³
• 300π cm³

Answer 1

300π cm³

Explanation:

The volume (V) of a cone is found using the formula

V =
`(1)/(3)` πr²h( r is the radius and h the perpendicular height )

here r = 10 and h = 9, hence

V =
`(1)/(3)` π × 10² × 9 =
`(900\pi )/(3)` = 300π cm³
