Find the Volume of a Cylindrical Candle

The video tutorial explains how to calculate the volume of a cylindrical candle using the formula V = πr²h. It provides a problem statement with a candle having a diameter of 6 inches and a height of 5 inches. The video guides viewers to pause and solve the problem, then walks through the solution step-by-step, explaining the formula and calculations. The radius is determined from the diameter, and the volume is calculated using π = 3.14. The final answer is 141.3 cubic inches. The tutorial concludes with encouragement to continue learning math.
