We have to assume that the hole is shaped like a cylinder, with a flat bottom.
Volume of a cylinder = (pi) R2 L = (area of the flat end) x (length).
Area of the circular flat end of the hole = (circumference)2/(4 pi)
(You don't see this formula too often. I worked it out in the process of doing
a lot of WikiAnswering, and it's a very convenient tool to have available.)
Volume of the cylindrical hole = (area of the end) x (length)
= (circumference)2 x (length)/(4 pi) = (182 x 1)/(4 pi) = 25.783 cubic feet = 0.955 cubic yard (rounded)
1 foot by 36 sq feet = 36 cubic feet of dirt is needed
There is 98.17477042 cubic feet of dirt in a 5 foot deep hole that is 5 foot across.

None. If it's a hole, then the dirt has been removed.

You will need 1500 cubic feet.
a lot of dirt.
if you mean a 30 foot diameter circle, then pi x 152 x 3 = 2119.5 cubic feet of dirt

To calculate the volume of dirt needed to fill a circular area, you first need to find the area of the circle (πr^2, where r is the radius). In this case, for a 14-foot circle, the radius is 7 feet. Once you find the area, you can calculate the volume of dirt needed based on the desired depth of filling the circle.

None, it's a hole! (1 cubic foot has been dug out.)

2.37 cubic yards of dirt is needed to fill an 8'X4' that is 24" deep garden box. If the box is filled 12 inches, the amount of soil needed is 1.19 cubic yards and that should be deep enough for most vegetables.
