Question

A hemisphere has a radius of 8 inches. Which methods will result in the surface area of the entire hemisphere?

halving the surface area of the related sphere
adding half the surface area of the related sphere and the area of the circular region
halving the radius, then determining the surface area of the related sphere
using the formula S = 3πr^2
using the formula S = 3πd^2

Answer 1

adding half the surface area of the related sphere and the area of the circular region

using the formula S = 3πr^2

Answer 2

Adding half the surface area of the related sphere and area of the circular region.

using the formula S = 3πr^2
