Well the basic calculation for volume would be all those measurements multiplied together L x W x H V. Visual in the figure below. Then find the radius of the circle at the top or bottom.
Va³ Thus you must multiply the dimensions of the side by itself 3 times.
First measure the diameter of the base usually easier than measuring the radius then measure the height of the cylinder. In the cell A2 we will enter different radii and after each input in the cell B2 we get the result of calculating the volume of spheres corresponding to its radii. Visual in the figure below. The equation for calculating the volume of a cylinder is shown below.
