WebMar 1, 2024 · The total surface area of the hemisphere is half the surface area of a sphere plus the area of the base of the hemisphere which is a circular base with radius r, in other words: 2. The hemisphere has a volume of kn cm^3 . Find the value of k. As I understand this question we want to know what is the value of k given the volume of a sphere, in ... WebSurface area of hemisphere = × surface area of sphere + area of base = × 4π r 2 + π r 2 = 3π r 2. Example: Calculate the surface area of a hemisphere with radius 4 cm. Solution: Surface area of hemisphere = × surface area …
