Volume = (area) x (depth)
27 cubic feet = 1 cubic yard
Area = (pi) (radius)2
Calling it "a 5 foot circle" is sloppy. You haven't said whether 5-ft is the radius,
the diameter, or the circumference. I'm going to assume that it's the diameter.
Area x depth = (pi) x (2.5)2 x (5) = 31.25 pi cubic feet = 3.6361 cubic yards. (rounded)

How many square feet are in 1 yard of concrete?
A yard of concrete is a measure of volume. A square foot is a measure of area. A cubic yard is 27 cubic feet of stuff. (3x3x3)To relate volume to area you must extend the area over a third dimension. One square foot that is one foot deep will equal one cubic foot. (1x1x1)So, a yard of concrete is 27 cubic feet or 3 feet tall 3 feet wide 3 feet deep. concrete wieghs 150lbs per cubic foot 27cubic feet times 150 pounds is 4050 pounds. This is 1 cubic yard of concrete.
