Question

The radius of a cone is 3 mm and the height is 21.3 mm. What is the volume of the cone? Use 3.14 for π. Round to the nearest tenth, if needed.

A) 200.6 mm3
B) 66.9 mm3
C) 200.65 mm3
D) 602 mm3

Answer 1

V = 1/3 * (pi) * r^2 * h
V = 1/3 * 3.14 * 3^2 * 21.3
V = 1/3 * 3.14 * 9 * 21.3
V = 1/3(601.938)
V = 601.938/3
V = 200.646 rounds to 200.6 mm^3
