A right triangle with sides 9 cm, 12 cm and 15 cm is rotated about the side of 9 cm to form a cone. The volume of the cone so formed is :
-
- 327 π cm³
- 330 π cm³
- 334 π cm³
- 324 π cm³
- 327 π cm³
Correct Option: D
Radius of cone so formed = 9 cm
Its height = 12 cm
| ∴ Volume of cone = | πr²h | |
| 3 |
| = | π × 9 × 9 × 12 | |
| 3 |
= 324π cu. cm.
