Calculating the Volume of a Cylinder:
If a cylinder has a flat bottom, meaning the height and radius meet at right angles, then this formula can be used to find of volume ('V') of that cylinder:
In plain english the volume of a cylinder can be calculated by squaring the radius, multiplying that value by PI, then multiplying by the height. You can also think of it as finding the area of a flat circle (PI * radius squared) and multiplying by the height to find volume.
Here is a step-by-step case that illustrates how to find the volume of a cylinder with a radius of 3 inches and a height of 5 inches. In this example PI will be 3.14.
- V = pi * r2 * h
- = pi * 32 * 5
- = pi * 9 * 5
- = 3.14 * 45
- = 141.37 cubic inches
