Question

The volume of a cone is 62.8 cubic inches. The height of the cone is 15 inches. What is the radius of the cone, rounded to the nearest inch? Use π = 3.14.

2 inches
4 inches
8 inches
9 inches

Answer 1

This is 2 right?

Answer 2

yes :) beacuse We know that, The volume of a cone V= (1/3)*Pi*r^2*h
here, volume is V= 62.8 cubic inches, Pi π = 3.14, The height of the cone h is 15 inches.
Make Radius r^2 as subject of equation in doing so, u get \[R=\sqrt{(3v)/(pie*h)}\]
