Question

A cone has a radius of 1.2 and a height of 2.9 inches. What is the volume, to the nearest tenth of a cubic inch, of the cone?. Explain or show ur work?

A. 3.6
B. 4.4
C. 10.6
D. 13.1

Answer 1

4.4 cubic inches

Explanation:

From the question;

• Radius of the cone is 1.2 inches
• Height of the cone is 2.9 inches

We are required to determine the volume of a cone;

Volume of a cone is given by the formula;

V=1/3πr²h

Therefore; taking π to be 3.142

Volume =1/3 × 3.142 × 1.2² × 2.9

= 4.373664

= 4.4 cubic inches (to the nearest tenth)

Thus, the volume of a cone is 4.4 cubic inches
