What is πr2h?

The formula ( \pi r^2 h ) represents the volume of a cylinder, where ( r ) is the radius of the base, ( h ) is the height of the cylinder, and ( \pi ) is a mathematical constant approximately equal to 3.14159. The term ( \pi r^2 ) calculates the area of the circular base, and multiplying this area by the height ( h ) gives the total volume of the cylinder. This formula is essential in geometry and is frequently used in various applications involving cylindrical shapes.
