What is the formula for the volume of a half circle?

Answer 1

Volume of a cylinder is (to find half, divide by 2):

Vcylinder = Abase * height

In a cylinder, the base is a circle and the area of a circle can be found:

Acircle = pi * radius2

After you find the area of the base, divide it by 2 then multiply it by the height and you'll find the volume of half a cylinder.

Answer 2

The volume of a cylinder (with a radius of r and a length l ) in the horizontal position filled to a depth (d) can be calculated with the following formula:

L(r2*(arcos((r-d)/r)) - (r-d)*sqrt(2rd-d2))

Note: Calculator must be set to work in radians as opposed to degrees.

Answer 3

The volume of a cylinder (with a radius of r and a length l ) in the horizontal position filled to a depth (d) can be calculated with the following formula:

L((r2)*(arcos((r-d)/r)) - (r-d)*sqrt(2rd-d2))


Note: Calculator must be set to work in radians as opposed to degrees

Answer 4

The formula for the volume of a half circle is (1/2) * π * r^2 * h, where r is the radius of the circle and h is the height of the half circle.

Answer 5

(4/3πr^3)/2 or the equation in parentheses divided by two.

Answer 6

circumference times 3.14 times height
