A cylinder has a radius of 3 inches and a height of 4 inches. What is the volume of the cylinder?

Step 1 ：The formula to find the volume of a cylinder is \(V = \pi r^2 h\), where \(r\) is the radius and \(h\) is the height.

Step 2 ：Substitute the given values into the formula: \(V = \pi (3)^2 (4)\)

Step 3 ：Calculate the volume: \(V = 36\pi\) cubic inches
