A solid consists of a cone on top of a cylinder with a radius equal to that of the cone. The height of the cone is 33 and the height of the cylinder is 13 . If the volume of the solid is 32 pi, what is the area of the base of the cylinder?

A= (32pi)/24=4/3pi

Explanation:

Volume of solid V = Axxh_(cy)+1/3xxAxxh_(co)
Where
Area of cylnder = area of cone = A
Height of cylinder =h_(cy)=13
Height of cone =h_(co)=33
Volume of the solidV=32pi
:. 18pi= Axx13+1/cancel3xxAxxcancel33^11=24A
:. A= (32pi)/24=4/3pi
