. What is the formula of Total Surface Area of a Hemisphere

Best Answer

The total area of hemisphere is defined as the sum of the space occupied by the curved area and the base of the hemisphere. The total area of ​​the hemisphere can be calculated by finding the total area of ​​its curved surface and base. It should be noted that the base of the hemisphere is circle. For a hemisphere, if its radius is given, its total area can be calculated by using the formula:

Surface area of a hemisphere = Curved Surface Area + Base Area = 2 π r2 + π r2 = 3 π r2

Where, r is the radius of the hemisphere.
