Vol. Of hemisphere is 2425.5cm^3. Find its CSA.(use π=22/7) |
|
Answer» Given : Volume of hemisphere = 2425.5\xa0cm3Volume of hemisphere = 2/3πr³2425.5 = 2/3*22/7*r³r³ = (2425.5*21)/44r³ = 50935.5/44r³ = 1157.625r = 10.5 cmNow,\xa0Curved Surface Area of hemisphere = 2πr²= 2*22/7*10.5*10.5= 693\xa0cm2CSA of hemisphere is 693 cm2 U can first find the radius of hemisphere as the volume is already given and after finding the radius, u can find its csa |
