a dog toy is constructed in the shape of a cylinder with a length of 6.8 in. The cylinder has a hemisphere at each end. The diameter is 19 in. Find the volume.

drwls,
19 is not a diameter. You probably made a typing error.
The volume will be pi[R^2*L + (4R^3)/3]
Get the radius R from the diameter.
