Question: what is the formula for volume and surface area of a hemisphere?
Answer: The sum of two hemispheres volumes is equal to the volume of a sphere. Therefore, the volume of its hemisphere is V=23r3×π V = 2 3 r 3 × π The surface area of the hemisphere is measured in units such as square centimeters (cm2) ( c m 2 ) , square meters (m2) , square kilometers (km2) ( k m 2 ) , etc.
