Cubic Yards Cylinder
Calculate cylinder volume in cubic yards from radius and height in feet. Free online construction calculator for concrete columns, excavation, and landscaping volume estimation.
About This Calculator
The Cubic Yards Cylinder Calculator computes the volume of a right circular cylinder in cubic yards. Enter the radius and height in feet, and the calculator applies the formula V = pir^2h to get cubic feet, then divides by 27 to convert to cubic yards -- the standard US construction volume unit.
This calculator is indispensable for contractors estimating concrete for cylindrical columns and footings, landscapers calculating topsoil or mulch for circular planters, excavation professionals determining fill material quantities, and construction estimators planning material orders.
The chart visualises the base area and height components, showing how they combine to produce the total volume. A breakdown bar chart displays the relationship between these two factors.
Frequently Asked Questions
How do you calculate cylinder volume in cubic yards?
First calculate the volume in cubic feet using V = pir^2h (with r and h in feet), then divide by 27 to convert to cubic yards. For example, a cylinder with radius 3 ft and height 6 ft has volume pi x 9 x 6 = 169.65 ft^3 ÷ 27 = 6.28 cubic yards.
How many cubic feet are in a cubic yard?
There are 27 cubic feet in one cubic yard (3 feet x 3 feet x 3 feet). This is the standard conversion for US construction and landscaping volume measurements.
What are common uses for cubic yards in construction?
Cubic yards are the standard unit for measuring concrete volume for foundations, slabs, and columns; estimating excavation and fill dirt quantities; landscaping materials like topsoil and mulch; and large-scale waste disposal or dumpster sizing.
How much concrete is needed for a cylindrical column?
Calculate the volume using V = pir^2h in feet, then divide by 27 to get cubic yards. For a column with 2 ft diameter (1 ft radius) and 10 ft height: V = pi x 1 x 10 = 31.42 ft^3 ÷ 27 = 1.16 cubic yards of concrete needed.
Is this cubic yards calculator free to use?
Yes, all calculators on Calculy are completely free to use. There are no registration requirements or usage limits.
