Gaurav Seth 7 years, 3 months ago

Given : Volume of hemisphere = 2425.5 cm³
Volume of hemisphere = 2/3πr³
2425.5 = 2/3*22/7*r³
r³ = (2425.5*21)/44
r³ = 50935.5/44
r³ = 1157.625
r = 10.5 cm
Now,
Curved Surface Area of hemisphere = 2πr²
= 2*22/7*10.5*10.5
= 693 cm²
CSA of hemisphere is 693 cm²

Anushka Jugran ? 7 years, 3 months ago

U can first find the radius of hemisphere as the volume is already given and after finding the radius, u can find its csa
