Surface Area of a hemisphere is 2772 cm2 then the total surface area of hemisphere is
surface area of hemisphere = 2772 cm²
2 Π r² = 2772
2 x (22/7) x r² = 2772
r² = 2772 x (1/2) x (7/22)
r² = 441
r = √21 x 21
r = 21
Total surface area of hemisphere = 3 Π r²
= 3 x (22/7) x (21)²
= 3 x (22/7) x (21) x (21)
= 3 x (22) x (3) x (21)
= 4158 cm²
Total surface area of sphere = 4158 cm²
