The volume of a sphere is
88 × (14)³ cm³ 21
. The curved surface of the sphere is (Take π = 22/7)
-
- 2424 cm²
- 2446 cm²
- 2484 cm²
- 2464 cm²
- 2424 cm²
Correct Option: D
| Volume of the sphere = | πr³ | |
| 3 |
or
| = | πr³ = | × (14)³ | ||
| 3 | 21 |
| or | × | × r³ = | × | × (14)³ | ||||
| 3 | 7 | 3 | 7 |
or r = 14
The curved surface of the sphere = 4rπ²
| = 4 × | × 14 × 14 = = 2464 cm². | |
| 7 |
