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. WebFeb 10, 2024 · 5. Multiply the equation by π. This is the last step to finding the volume of a sphere. You can leave π as it is, stating the final answer as V = ⁴⁄₃π. [8] Or, you can plug π into your calculator and multiply its value by 4/3. The value of π [9] (approximately 3.14159) x 4/3 = 4.1887, which can be rounded to 4.19.
