equation for finding the volume of a sphere. The formula to find the volume of a sphere you use the formula. To calculate the volume of a sphere the following formula is used where V volume and r radius.
Where r is the radius of the sphere. Visual on the figure below. The volume of a sphere is equal to four-thirds of the product of pi and the cube of the radius.
The volume of a sphere is 43 x p x diameter 2 3 where diameter 2 is the radius of the sphere d 2 x r so another way to write it is 43 x p x radius 3.
To calculate the volume of a sphere you need to know its radiusthe distance from its center to its surface. V frac 4 3pi r3 where r is the radius. If youre given the diameter. In the figure above drag the orange dot to change the radius of the sphere and note how the formula is used to.
