A conical tent of radius, 3m and height 4.2m, was assembled by the boy scouts. How much or does it enclose?

The formula for the volume of a right circular cone is V=1/3(pi)r^2h where r is the radius of the base and h the vertical distance from the base to the apex.

We are given r=3m and h=4.2m so we can compute the volume:

or the volume is approximately
