4 inches = 1/3 foot
Volume = (500 ft2) x (1/3 ft) = 500/3 ft3 = 1662/3cubic feet

Assuming the 28 feet refers to the diameter of the circle, the answer is 1231.5 cubic feet, approx.
Without depth, the circle is a flat figure without volume ... zero cubic units.
33.5 cubic feet.
It depends upon whether the 24' is the radius, diameter or circumference.
5200 cubic feet
if you mean a 30 foot diameter circle, then pi x 152 x 3 = 2119.5 cubic feet of dirt
24 cubic feet = 0.89 cubic yards
You don't. Cubic feet is a measure of volume. Volume is a property of 3-dimensional objects. A circle is a two-dimensional object, it does not have a volume. You could find the cubic feet in a sphere, but not in a circle.
The question doesn't say it, so we'll assume that a "120 feet circle" means thatthe diameter is 120-ft, i.e. the distance all the way across, through the center.Area of the circle = pi R2 = 3,600 pi square feet.If the dirt is one inch deep, then the volume is (3,600 pi) / 12 cubic feet = 34.907 cubic yards. (rounded)The answer is: 34.907 cubic yards (rounded) for every inch the dirt is deep.
9.27 cubic feet
If you are asking for "square" feet, the depth is irrelevent. The area would be 85 square feet If you want a figure which takes the depth of 4 inches into the account, the number of "cubic feet" would be roughly 28 cubic feet.
