What you need to do, is find the area of both of the cones and add them together.

Answer 13

Do you know the formula for the area of a cone?

Answer 14

oops, I mean volume

Answer 15

\[V=\frac{ 1 }{ 3 }\Pi r ^{2}h\]

"Garden Landscaping Company purchases some of the gravel. The remaining pile has a radius of 4 ft and a height of 5 ft."
