Enter the radius into the calculator to determine the volume of the stone. This calculator can also evaluate any of the variables given the others are known.

## Stone Volume Formula

The following formula is used to calculate the volume of a stone.

V = 4/3 * π * r^3

Variables:

• V is the volume of the stone (cubic units) π is a constant, approximately equal to 3.14159 r is the radius of the stone (units of length)

To calculate the volume of a stone, cube the radius of the stone, then multiply the result by π (approximately 3.14159). Multiply this result by 4/3 to get the volume.

## How to Calculate Stone Volume?

The following steps outline how to calculate the Stone Volume using the given formula:

1. First, determine the radius of the stone (r) in units of length.
2. Next, square the radius (r^2).
3. Next, multiply the squared radius by π (π * r^2).
4. Next, multiply the result by 4/3 (4/3 * π * r^2).
5. Finally, calculate the Stone Volume (V).
6. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge:

radius of the stone (r) = 5 units

π (constant) = 3.14159
