What is the volume of this right cone?

27π cm³
200π cm³
213π cm³
300π cm³

Answer 1

Hello!

The volume of a cone is Volume = 1/3πr²h.

V = 1/3π(10)²(9)
= 1/3π100(9)
= 1/3π900
= 300π cm³

Therefore, the volume of this right cone is 300π cm³.

Answer 2

The correct option is 4.

Explanation:

Given information: r=10 cm, h=9 cm and l=13.5 cm.

The volume of right cone is

`V=(1)/(3)\pi r^2h`

Where, r is the radius of base and h is the height of the cone.

`V=(1)/(3)\pi (10)^2(9)`

`V=\pi* 100* 3`

`V=300\pi`

The volume of cone is 300π cm³, therefore option 4 is correct.
