a cylinder with a radius r and height h is topped by a cone whose height is the same as that of the cylinder.
which formula can be used to find the volume of the composite solid?
:
Vol of cylinder: V+=+pi%2Ar%5E2%2Ah
Vol of a cone: V+=+%281%2F3%29pi%2Ar%5E2%2Ah
:
Since h and r are the same, add one to 1/3:
V = %284%2F3%29%2Api%2Ar%5E2%2Ah
