Question

Find the volume of the cone below.

Answer 1

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

For this case we know that the radius is r=7cm and the height is h =11cm. And replacing we got:

`V=(1)/(3) \pi (7cm)^2 (11cm)= (1)/(3) \pi (49cm^2) (11 cm)=(539)/(3) \pi cm^3`

And the best option would be:

`V = (539)/(3) \pi cm^3`

Explanation:

For this case we know that the volume of the cone is given by:
