how to volume of a sphere

The volume of a sphere can be calculated using the formula V = (4/3) * π * r^3, where V is the volume, π is a constant approximately equal to 3.14159, and r is the radius of the sphere.

1. First, measure the radius of the sphere.
2. Square the radius by multiplying it by itself.
3. Multiply the squared radius by π.
4. Multiply the result by 4/3.

For example, if the radius of the sphere is 5 cm, the volume would be calculated as follows:
V = (4/3) * 3.14159 * 5^3
V = (4/3) * 3.14159 * 125
V = 4.18879 * 125
V = 523.598 cubic centimeters

Therefore, the volume of a sphere with a radius of 5 cm is 523.598 cubic centimeters.
