WebNov 9, 2015 · To find the volume of our cylinder, we need to multiply the area of the top by the total height of the cylinder. In other words; V = π(radius of cylinder)2(height of cylinder) V = π(√r2 −h2)2 (2h) V = 2πh(r2 − h2) This is our volume function. Next we take the derivative of the volume function and set it equal to zero. WebSep 7, 2024 · So, the volume will be ‘ (area of base) × height of the cylinder’. Since the base of a cylinder is a circle, the volume can be written as: Volume = πr2 × h. Hence, the volume of a cylinder = πr2h cubic units. where: Π (Pi) = 3.142. r = radius of the base of cylinder. h = height of cylinder.
