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 × 𝑟 … Web5. feb 2024 · 1. There are different ways to do this. One of the ways is to divide the sphere into N sectors of equal width, like segments of an orange. Each of the N pieces will have equal surface area. Another way is to divide the sphere into N sectors of equal width, and then to divide along the equator, so that each will be a half-segment.
WebSurface Area of a Sphere: The surface area of a sphere is four times the area of the largest cross-sectional circle, called the great circle. SA = 4πr2 = πd2 SA = surface area; r = radius of sphere; d = diameter of sphere See applications of spheres under Modeling.
