The answer is 400pi because the area of a cone is A=1/3*pi*r^2*h

1/3*pi*100*12 = 400pi

Answer:

Volume of cone is 400π cm³

Explanation:

Given : a right cone with base radius = 10 cm , height = 12 cm and lateral height 15.6 cm

We have to find the volume of this right cone.

Volume of cone =
(1)/(3)\pi \cdot r^2 \cdot h

Substitute , we get,

Volume of cone =
(1)/(3)\pi \cdot (10)^2 \cdot 12

Volume of cone =
\pi \cdot 100 \cdot 4

Volume of cone =
400 \pi

Thus, option (3) is correct.

Thus, Volume of cone is 400π cm³
