Volume of a sfeer

The formula for calculating the volume of a sphere is given by:

V = (4/3)πr³

where "V" is the volume of the sphere and "r" is the radius of the sphere.

The formula for calculating volume varies depending on the shape of the object. Here are the formulas for calculating the volume of common geometric shapes:

1. Cube: The formula for the volume of a cube is V = s^3, where "s" represents the length of one of its sides.

2. Rectangular Prism: The formula for the volume of a rectangular prism is V = l × w × h, where "l", "w", and "h" represent the length, width, and height of the prism, respectively.

3. Cylinder: The formula for the volume of a cylinder is V = πr^2h, where "r" is the radius of the base of the cylinder and "h" is the height of the cylinder.

4. Sphere: The formula for the volume of a sphere is V = (4/3)πr^3, where "r" is the radius of the sphere.

5. Cone: The formula for the volume of a cone is V = (1/3)πr^2h, where "r" is the radius of the base of the cone and "h" is the height of the cone.

Remember to use the correct units of measurement when plugging in values for the variables in these formulas.
