# How to Calculate the Volume of a Cylinder

No matter the size, you can use the same simple formula to determine the volume of a cylinder.

### Instructions

- Step 1:
**Write down the dimension**Write the height and diameter of the cylinder on a piece of paper. - TIP: If you have a diameter measurement, divide the diameter by 2 to get the length the radius.
- Step 2:
**Square the radius**Square the radius, or the distance from the center of the base to the outside edge. - Step 3:
**Multiply the product**Multiply the product of the radius squared by pi. This will give you the area of the base of the cylinder. - TIP: Use 3.14 to represent pi if you don't have a scientific calculator.
- Step 4:
**Multiply the base by the height**Multiply this number by the height of the cylinder to determine the volume. - Step 5:
**Write the product in cubic units**Write the product as a measure of cubic units. - Step 6:
**Work backwards to check your solution**Work backwards to check your solution. Use the formula "volume equals pi times radius squared times height" for future calculations. - FACT: The most definitive and influential book written about geometry was written by Euclid, a Greek mathematician during the third century BCE.
