Find the volume of the cone 3ft and 2 ft. Round your answer to the nearest tenth if necessary. Use 3.14 for pie

Answer:

37.68 ft^3

Step-by-step explanation:

The parameters used in describing a cone is radius and height

Hence

Radius= 3ft

Height = 2 ft

The volume of a cone is given as

$v=\frac{1}{3} \pi r^2 h$

substitute

$v=\frac{1}{3}*3.14*3^2*2^2\\\\v=\frac{1}{3}*3.14*9*4\\\\v=\frac{1}{3}*113.04\\\\v=37.68 ft^3$

Hence the volume is 37.68 ft^3
