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.

r = d/2

r = 15.6/2

r = 7.8 in.

thus the radius of the right circular cone is 7.8

v = 1/3 (3.14) (7.8) ^2 (12.4)

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

v = 2368.866/3

v = 789.622

thus the volume of the right come is 789.622 cubic inches
