To calculate the volume of a cylinder you need to know its height and the area of its base. Enter this in field marked RADIUS below. The formula for the volume of a cylinder circular prism is derived from the volume of a prism where r is the radius and h is the heightlength.
To calculate the volume of a cylinder we need to know the radius of the circular cross-section of the cylinder - this is the measurement from the centre of the circle to the outer-edge.
Since the end base of a cylinder is a circle the area of that circle is given by the formula. Keep in mind that when you have a cylinder the diameter is a doubled radius. To calculate the volume of a cylinder you must know its height and the radius of the circular base the distance from the center of the circle to its edge at the top and bottom. Volume pr 2 h.
