Given the radius of a hemisphere calculate the volume curved surface area circumference and total surface area. The total surface area of hemisphere is equal to sum of half of surface area of sphere and area of its circular base. S tot total surface area.
Total surface area of a hemisphere is 2pr 2 pr 2.
S lat lateral surface area. The surface area of a sphere of radius r is 4 p r 2. It also refers to half of the earth such as the Northern Hemisphere and Southern Hemisphere. Total surface area of hemisphere 2 p r 2 p r 2 3 p r 2.
