Sandra has a cylinder poster roll that measures 24in in length and 4in in diameter. What is the volume of the cylinder?

Answer 1

First, we need to calculate the radius of the cylinder using the formula:

radius = diameter / 2
radius = 4in / 2
radius = 2in

Next, we can calculate the volume of the cylinder using the formula:

volume = πr^2h
volume = π(2in)^2(24in)
volume = π(4in^2)(24in)
volume = 96πin^3

Therefore, the volume of the cylinder is 96π cubic inches.
