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.
