Sphere Volume Calculator

The formula for its volume equals: volume = (4/3) * π * r³. Usually, you don't know the radius - but you can measure the circumference of the sphere instead, e.g., using the string or rope. The sphere circumference is the one-dimensional distance around the sphere at its widest point. circumference = 2 * π * r, so r = circumference / (2 * π)
