To decorate the area around the pool with flowers, your neighbor purchases conical urns of radius 1.5 ft and height 3 ft. how much soil must he buy to fill each urn?

To get the amount of soil required to fill the urn, we need to get the volume of the urn. Given that the urn is cylindrical in shape, the volume will be given by:
V=πr^2h
radius=1.5 ft
height=3 ft
thus;
V=π*1.5^2*3
V=21.2058 ft^3
The answer is V=21.2058 ft^3
