The height of cone is 12 inches

Solution:

The volume of cone is given as:


V = ( \pi r^2h)/(3)

Where,

r is the radius

h is the height

From given,

r = 3 inches

V = 113.04 cubic inches

Substituting we get,


113.04 = ( 3.14 * 3^2 * h )/(3)\\\\113.04 = 3.14 * 3h\\\\113.04 = 9.42h\\\\h = 12

Thus the height of cone is 12 inches
