Calculating Cylinder Volume and Area

The video tutorial explains how to calculate the volume of a cylinder. It begins by introducing the formula for volume, which is the base area times the height. The base area is calculated as pi times the radius squared. The tutorial provides an example with a cylinder having a radius of 5 inches and a height of 15 inches. It walks through the calculation step-by-step, using 3.14 as the value of pi, and arrives at a final volume of 1177 cubic inches.
