Question

HELP URGENTLY!! CALCULATE THE VOLUME OF THE CONE

Answer 1

First, find the height of the cone. Use the Pyth. Thm. for this calculation:

15^2 + h^2 = 25^2, or 225 + h^2 = 625. Then h^2 = 400 and h = + 20 units.

The voume formula applicable here is

V = (1/3)(base)(height).

Specifically,

V = (1/3) π(225)(20) units^3

= 1500*pi units^3
