WebThe formula for the volume of a sphere is V = 4/3 π r³, where V = volume and r = radius. The radius of a sphere is half its diameter. So, to calculate the surface area of a sphere given … 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.
WebAnswer. Recall that the surface area, 𝐴 , of a sphere of radius 𝑟 is given by the formula 𝐴 = 4 𝜋 𝑟. . Here, we are given the diameter of the sphere, 12.6 cm, which is twice its radius. To apply the formula to work out the surface area, we first need to calculate the radius, so we halve the diameter to get 𝑟 = 1 2. 6 ÷ 2 = 6.
