Surface area of a hemisphere
WebThe total surface area of a hemisphere is the sum of its curved surface area and base surface area. Curved surface area of a hemisphere = \ ( 2\pi~r^2\) [Half of the surface area of a sphere with radius r] Area of base = \ ( \pi~r^2\) [Circle shaped base with radius \ (r\)] Total Surface Area (TSA) = Curved Surface Area + Area of Base WebThe surface area of a hemisphere is the curved part of the hemisphere and we calculate it by using this formula, Surface Area of Hemisphere = 3πr2, where π which is taken as …
