A right circular cone stands on a hemisphere. The base radius of the cone is equal to the radius of the hemisphere. If the base radius of the cone is 10 centimeters and its height is 15 centimeters,calculate the total volume of the solid.

Answer 1

cone: 1/3 πr^2 h
hemisphere: 2/3 πr^3
sum: πr^2/3 (h+2r)

Now just plug in your values.
