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.

You will need

  • Dimensions of a cylinder
  • Paper
  • Pencil
  • Scientific calculator (optional)

Step 1 Write down the dimension Write the height and diameter of the cylinder on a piece of paper.

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.

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.
