OK, formula for volume of a cylinder is (pi)(r-squared)(h)
pi is 3.14, approximately
r (radius) is 4 ft., r-squared is 4X4=16
h (height) of 3 inches is 0.25 ft.
3.14X16X0.25 = 12.56
the units were all in feet, so answer is in cubic feet, 12.56 cubic feet. A circle is two-dimensional, so zero. If you mean a cylinder, then... Volume = Base Area * height
=Pi * radius^2 * height
=3.14 * (8 ft/2)^2 * (3 in/12 in/ft)
= 12.56 cubic feet

How many cubic feet in a circle with a ten foot diameter and eight inches high?
That's actually a cylinder.8 inches = 2/3 footThe volume of a cylinder is (pi) (radius)2 (height) = (pi) (5)2 (2/3) = 52.36 cubic feet (rounded)
What is the area of a circle that has a diameter of eight inches?
The area of a circle is the number pi (3.14159...) times the square of the radius. The radius is half the diameter. So if the diameter is 8 inches, the radius is 4 inches. Squaring that gives us 4 x 4, or 16 square inches. Multiplying 16 by pi equals an area slightly larger than 50.26 square inches.
What is the surface area of a cylinder that a diameter of eight inches and a height of five inches?
A cylinder with a diameter of eight inches and a height of five inches has a surface area of 226.2 square inches.
How many square inches in a eight inch circle?

If circle circumference is 8 what is diameter?
If you divide eight by pi, you get 2.54647909 as the diameter. If you divide eight by 3.14 (simplified pi), you get 2.54777070 as the diameter.
What is the radius of the circle with the diameter of eight inches?
4 inches
If the area of a circle is about twenty-eight square inches what is the diameter?
If the area of a circle is about 28 square inches the diameter is: about six inches (5.971).
What does diameter of a circle equal if the radius is eight inches?
16 inches
What is the radius of a circle with a diameter of eight inches?
4 inches The radius of a circle is always half of its diameter (so 8in/2 = 4 in).
How can you find the diameter of a circle with an approximate circumference of thirty-eight inches?
Divide the circumference (38") by Pi (about 3.1416) to get the diameter in inches.
What would be the radius of a circle with a diameter of 8 inches?
Radius is one-half of the diameter of a circle. Therefore, the radius of an eight-inch diameter circle is four inches. The diameter of a circle is a straight line joining a point on the circumference through the centre to the 'opposite' point on the circumference.
