Question

Estimate the volume of material in a cylindrical shell with a height of 28 in., radius of 5 in., and a shell thickness of 0.6 in.

Answer 1

\[V=\pi r^{2}h\]
Just subtract 0.6 inches from the radius, and 2(0.6) inches from the height, and it should give you your answer.

\[V=\pi (5-0.6)^{2}(28-(2\times0.6))\]
\[V \approx 519\pi\]
