Answer 2

Follow this logical sequence.

1) Diameter is 8"
2) What is the Radius? Reference: Radius = Diameter / 2 -- Standard Formula
3) What is the Height? Reference: Height = 3 * Radius -- Given in the problem statement.
4) What is the Volume? Reference: \(Volume = \pi r^{2}h\) -- Standard Formula

Answer 3

Whenever I reference "standard formula", this means you should commit this to memory.
