WebFind the total surface area of a hollow hemisphere whose inner and outer radii are 7 cm and 8 cm, respectively. Solution: Let the inner and outer radii of the hemisphere be r1 and r2, respectively. Then r1 = 7 cm and r2 = 8 cm The total surface area of a hollow cylinder = 2𝜋 (r22 + r12) + 𝜋 (r22 – r12) = 2𝜋 (82 + 72) + 𝜋 (82 – 72) 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 …
