Question

An oblique cone has a radius of 4 units, a height of 8.5 units, and a slant length of 11.7 inches.
What is the volume of the oblique cone? Round to the nearest tenth.

142.4 cubic units
142.4 square units
196.0 cubic units
196.0 square units

Answer 1

Volume of any cone (right or oblique) = (1/3)πr^2h. With r = 4 and h = 8.5:

V = (1/3)π(4^2)(8.5) = (136/3)π ≈ 142.4

So the correct choice is: 142.4 cubic units.
