If the height of a cone is 7 cm and the diameter of the circular base is 12 cm, then its volume is (nearest to integer):
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 264 cm3.
Volume of cone = 1/3πr2h
here, r = radius of cone and h = height
Now, according to the question
Volume of cone = 1/3 × 22/7 × 62 × 7
⇒ 1/3 × 22/7 × 6 × 6 × 7
⇒ 22 × 6 × 2 = 264 cm3
