Question

Hector is finding the volume of a cone and the volume of a cylinder. Both the cone and the cylinder have a radius of 3 inches and a height of 5 inches. What is the volume, in cubic inches, of the cone?

Answer 1

the volume of the cone is

15in^3

Explanation:

Step one:

parameters of the cone

radius r = 3 in

height h= 5 in

Step two:

the expression for the volume of the cone is

V= 1/3πr^2h

substitute

`V= 1/3*3.142*3^2*5\\\\V=1/3*45\\\\V=15 in^3`
