The volume of hemisphere is 2425 1/2cubes. Find its curved surface area |
| Answer» Volume of hemisphere = 2425 1/2 cu cm or 2425.5 cu cm.Volume of hemisphere = 2/3πr³2425.5 = 2/3× 22/7× r³r³ = (2425.5×21)/44r³ = 50935.5/44r³ = 1157.625r = 10.5 cmNow,Curved Surface Area of hemisphere = 2πr²= 2 × 22/7 × 10.5 × 10.5= 693 sq cmCSA of hemisphere is 693 sq cm. | |
