Question

Find the volume of a right circular cone that has a height of 12.4 in and a base with a

diameter of 15.6 in. Round your answer to the nearest tenth of a cubic inch.

Answer 1

789.6 in³

Explanation:

r=d/2

r=15.6/2

r=7.8 in

Then Volume=1/3pier²h

1/3(3.14)(7.8)²(12.4)

1/3(3.14)(60.84)(12.4)

2368.866/3

=789.622

=789.6 in³
