The volume of a right circular cylinder whose height is 40cm, and circumference of its base is 66 cm, is :
-
- 55440 cm³
- 3465 cm³
- 7720 cm³
- 13860 cm³
- 55440 cm³
Correct Option: D
Circumference of the base, C = 2πr
where, r = radius of the base
| ⇒ r = | ||
| 2π |
Given; C = 66cm, h = 40cm Volume = πr²h
| = π |  |  | ² | h = | ||
| 2π | 4π |
| = | cm³ | ||||
| 4 × | 22 | ||||
| 7 | |||||
= 7 × 3 × 66 × 10 cm³ = 13860 cm³
