Question

Find the volume of a cone with a height of 6cm and a base radius of 4cm. Use the value 3.14 for π, and do not do any rounding.

Answer 1

100.48 cm³

Explanation:

Volume of a cone, V = 1/3 * pi * r² * h

Radius, r = 4 cm ; h = 6cm

V = 1/3 * 3.14 * 4² * 6

V = 1/3 * 3.14 * 16 * 6

V = 3.14 * 16 * 2

V = 3.14 * 32

V = 100.48 cm³

Hence, the volume of the cone is 100.48 cm³
