Question 55966 • Reading HS- Integrated Math I
The great-circle circumference is 2πr, so 2πr = 12π gives a radius of 6 inches. A hemisphere’s total surface area includes its curved surface and circular base, so it is 3πr² = 3π(6²) = 108π square inches. Therefore, the true statements are that the radius is 6 inches and the total surface area is 108π square inches.
