Question

anonymous · Answer

Find the volume of the outer cylinder and subtract the volume of the inner cylinder.  Then convert to cm^3

anonymous · Answer

Volume of a cylinder = pi * r^2 * h

anonymous · Answer

[(pi * 1.1^2 * 48) - (pi * 1^2 * 48)] * (2.54cm/1in)^3

anonymous · Answer

Make sure to cube 2.54
