If you know the surface area of a sphere, you can find its volume by using the formula V = (4/3) * π * (r^3), where r is the radius of the sphere.
To find the radius, you can use the formula A = 4 * π * (r^2), where A is the surface area of the sphere. Rearrange the formula to solve for r, which gives you r = √(A / (4 * π)).
Once you have found the radius, you can substitute it back into the formula for the volume to calculate the volume of the sphere.
