To do this we simply take the definite integral of the disk area formula from above for all possible heights z which are between -r at the bottom of the ball and r at the top of the ball. The volume of a sphere is nothing but the space occupied by it. Notice that the 43 fraction and pi are numerical constants.
In this post we will derive the following formula for the volume of a ball.
See Length of Arc in Integral Calculus for more information about ds. That is our volume is given by. Therefore the volume of the hemisphere volume of cylinder - volume of cone p R 3 - 13 p R 3 23 p R 3 The volume of the sphere is twice that. The volume and surface area of a sphere are given by the formulas.
