Question

If the radius of the base of right circular cone is 3r and its height is equal to the radius of base than its volume is

Answer 1

Here is your answer!!! Hope it helps!!!

Answer 2

The volume of the cone is 198r³/7

Given data :

Radius = Height = 3r

So,

Volume = 1/3 × π × (radius)² × height = 1/3 × 22/7 × 3r × 3r × 3r

= 22/21 ×27r³

= 22/7 ×9r³

= 198r³/7 (answer)
