Semicircle - Volume

vCalc Reviewed

$V = 1/2 pi r^2 h$

$(h)"Height of Semicircle"$

$(r)"Radius of Semicircle"$

The Math / Science

The formula for the volume of a semicircle is:

V = ½•π•r²•h

where:

V is the volume of the semicircle
h is the height of the semicircle
r is the radius of the semicircle

Volume of a uniformed shaped object such as an octagon column is derived by the following formula:

Volume = Area • Height

The formula above uses the area of a semi-circle.

Volume is a three dimensional measurement of the amount of space taken up by an object. Volume units are cubic measurements for solid objects such as cubic inches and cubic meters. Fluids have separate volume units such as liters, fluid ounces, cups, gallons, and barrel.

The volume of an object can measured by the liquid it displaces or be calculated by measuring its dimensions and applying those dimensions to a formula describing its shape. Many such calculations are available in the following list of calculators.

In many cases, the calculators are for a column with a geometric shaped base and vertical sides. One basic formula for volume is area times a Height when the volume has vertical sides.
