Question

Consider the volume of the region shown below, which shows a right circular cone with a top radius of 3 cm and height 9cm

Answer 1

84.82 cm

Explanation:

Volume of a cone:
`(1)/(3) \pi r^2h`

`(1)/(3) \pi r^2h\\\\\\\\= (1)/(3)\pi (3)^2(9)\\\\= (1)/(3)\pi(9)(9)\\\\\\\= (1)/(3) \pi (81)\\\\= 27\pi \\`

≈ 84.82 cm
