Question

Find the volume of a right circular cone that has a height of 12.5 m and a base with a radius of 2.2 m. Round your answer to the nearest tenth of a cubic meter.

Answer 1

Answer: 63.4

Explanation:

You round to the tenths giving you 63.4

Answer 2

The volume of the cone is 63.3m³

Step-by-step explanation:

First of all to solve this problem we need to know the formula to calculate the volume of a cone

v = volume

r = radius = 2.2m

h = height = 12.5m

π = 3.14

v = 1/3 * π * r² * h

we replace with the known values

v = 1/3 * 3.14 * (2.2m)² * 12.5m

v = 1/3 * 3.14 * 4.84m² * 12.5m

v = 63.32m³

rount to the neares tenth

v = 63.32m³ = 63.3m³

The volume of the cone is 63.3m³
