# How do you calculate the volume of a semicircle?

The Math / Science

1. The formula for the volume of a semicircle is:
2. V = ½•π•r²•h.
3. Volume of a uniformed shaped object such as an octagon column is derived by the following formula:
4. Volume = Area • Height.
5. The formula above uses the area of a semi-circle.
6. For the volume of polygon based objects (columns), see the following:

.

Then, how do you find the volume of a semicircle prism?

V = (pi * radius * radius * h)/2 = pi R^2 h/2,where h is the hight. In fact this formula is for a cylinder volume divided by 2. As it is seen the the result is in cubic units(m^2 x m=m^3). Either you’re asking how to find the volume of a *hemisphere* (3D) or the *area* of a semicircle.

One may also ask, what is the formula for volume? Volume of a cube = side times side times side. Since each side of a square is the same, it can simply be the length of one side cubed. If a square has one side of 4 inches, the volume would be 4 inches times 4 inches times 4 inches, or 64 cubic inches. (Cubic inches can also be written in3.)

In this way, how do you find the volume of a partial cylinder?

The volume of a cylinder is V = π r2 h where π is approximately 3.14159, r is the radius of the circular end and h is the height if the cylinder is standing on end. For your barrel r = 36/2 = 18 inches and h = 60 inches. Thus the volume is V = 61072.56 cubic inches.

What is the formula for the volume of a prism?

The formula for the volume of a prism is V=Bh , where B is the base area and h is the height. The base of the prism is a rectangle. The length of the rectangle is 9 cm and the width is 7 cm.
