Cylinder Cubic Yardage Calculator

Using the Cylinder Cubic Yardage Calculator

This calculator is perfect for finding the cubic volume of a cylinder, given the radius or the diameter and the height. This is useful for determine cubic yardage for concrete projects, filling sonotubes, posts, or footings, building and construction projects, or landscaping projects. This is also helpful for anyone trying to find the volume of a cylinder. Estimate the cost for materials to fill the cylinder by entering a price per cubic yard.

How to Find the Cubic Yardage of a Cylinder

The cubic volume of a cylinder is found by multiplying the radius times the radius times pi times the height.

• Find the radius and height. If the diameter is known then divide the diameter by 2 to get the radius. The radius and height should be in yards, if you have other measurements convert to yards.
• Convert inches to yards, convert feet to yards, or convert meters to yards
• Multiply the radius of the cylinder times the radius, eg. r²
• Multiply times π to get the area of the circle
• Multiply times the height of the cylinder to get the volume
• Multiply the cubic yardage by the price per cubic yard to get the cost of materials, if required

Circle

area = π × (diameter ÷ 2)²
area = π × r²

π = 3.14159265359

Cylinder

volume = π × (diameter ÷ 2)² × height
volume = π × r² × h

π = 3.14159265359
