Radius: r

Height: r%2B7

Volume: V

-------------------------------------------------------

Volume of Cylinder: V+=+pi%2Ar%5E2%2Ah

Replace h with r+7: V+=+pi%2Ar%5E2%2A%28r%2B7%29

The volume expression is pi%2Ar%5E2%2A%28r%2B7%29

A cylinder with radius r units and height h units has a volume of cubic units given by:
pi%2Ar%5E2%2Ah
if a height 7in greater than the radius, we have:
h=r%2B7in....substitute in
pi%2Ar%5E2%2Ah
pi%2Ar%5E2%2A%28r%2B7in%29
