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 the diameter of the sphere, you can first calculate the radius, then the volume. Created by Sal Khan and Monterey Institute for Technology and Education. Sort by: WebHere, 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. 3. Then, substituting for 𝑟 in the formula, we have 𝐴 = 4 × 𝜋 …
