Many homes' sizes are measured by the number of square feet that the property encompasses. However, for large properties and tracts of land like farms, square feet are an impractical measurement...

Density is the amount of mass an object has per each unit of volume. Density is key in the principle of buoyancy, which is credited to Archimedes. It is also used in determining which material to...

Geometric formulas involving the radius are usually written expecting that you know the radius and you are trying to find another aspect of the circle or sphere, such as the area or volume....

Cylinders are three-dimensional shapes that have two circles as bases and are connected by parallel lines to enclose the space between them. The volume of the cylinder is the empty space enclosed...

A sphere is a three-dimensional object that is formed by connecting all points that are a specified distance away from a single center point. The volume of a sphere is the amount of space enclosed...

By definition, a sphere is formed by all points that are a certain distance away from the center. The shape results in a three-dimensional round object, such as a racquetball or bowling ball...

Finding the volume of a pipe can be useful for any number of reasons such as calculating how much water a pipe can hold before bursting. There are multiple ways to find that volume, depending on...

The density of an object has many applications including uses as a flotation device or how less dense materials can be used to make everyday items lighter and easier to carry. In order to know the...

Circumference is the distance around a circle. The steps for calculating circumference can be used to solve real life problems. For example, a jogger interested in knowing the distance around a...
