WebCurved Surface area of a hemisphere =2πr 2=2× 722×21×21=2772cm 2Total surface area of a hemisphere =3πr 2=3× 722×21×21=4158cm 2. WebThe full formula for surface area is derived by the following steps: 1.) Surface area of a sphere: SA = 4πr 2 2.) Area of a circle: πr 2 3.) Surface area of a hemisphere: SA = 2πr 2 + πr 2 4.) Simplifying this gives us the following: 5.) SA = 3πr 2. Note how the surface area of a sphere is divided by two before being added to the circle area.
