What is the volume of a cylinder with a base radius of 8 inches. and a height of 40 inches? Leave your answer in terms of pi.
The volume of a cylinder is given by the formula V = πr^2h, where r is the base radius and h is the height.
Plugging in the values, V = π(8^2)(40) = 2560π cubic inches.
Therefore, the volume of the cylinder is 2560π cubic inches.
