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. WebEnter the radius, diameter, surface area or volume of a Sphere to find the other three. The calculations are done "live": How to Calculate the Volume and Surface Area. Surface Area …

WebDec 1, 2024 · Some of you may have seen in school that the surface area of a sphere is 4\pi R^2 4πR2, a suspiciously suggestive formula given that it’s a clean multiple of \pi R^2 πR2, the area of a circle with the same radius. But have you ever wondered why is this true? And I don’t just mean proving this 4\pi R^2 4πR2 formula.
