height of a right circular cone

Question

If the volume of a right circular cone is 77.44π in³, and if the radius of the base is 4.4 in, what is the height?

Answer 1

Hi,

As you know the volume of cone is:

V = 1/3 pi r^2 h Now, replace all given information to this equation,

77.44π in³= 1/3 pi (4.4)^2 h then solve equation for h

h = 3.819 inches

I hope it is useful,
