WebNov 7, 2024 · 4. Find the radius from the surface area. Use the formula r = √ (A/ (4π)). The surface area of a sphere is derived from the equation A = 4πr 2. Solving for the r variable yields √ (A/ (4π)) = r, meaning that the radius of a sphere is equal to the square root of the surface area divided by 4π.
