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. WebThe circumference is pi times the diameter if it were opened up and straightened out to a line segment. The circumference of a circle can be found by multiplying pi ( π = 3.14 ) by the diameter of the circle. If a circle has a diameter of 4, its circumference is 3.14*4=12.56. If you know the radius, the diameter is twice as large. mariana zapata interview
