From a solid cylinder whose height is 12 cm and diameter 10cm, a conical cavity of same height and same diameter of the base is hollowed out. The volume of the remaining solid is approx imately (π = 22/7)
-
- 942.86 cm³
- 314.29 cm³
- 628.57 cm³
- 450.76 cm³
- 942.86 cm³
Correct Option: C
Volume of solid cylinder = πr²h
| Volume of cone = | π r² h | |
| 3 |
| Difference = π r²h – | π r² h | |
| 3 |
| = | π²h = | × | × 5 × 5 × 12 = 628.57 cu.cm. | |||
| 3 | 3 | 7 |
