What is the volume of a cone whose base diameter is 12 cm and the height is 21.7 cm?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 818.4 cm³.
Given:
Diameter of the cone = 12 cm
Radius of the cone (r) = 12/2 = 6 cm
Height of the cone (h) = 21.7 cm
Formula used:
Volume of the cone = (1/3)πr2h
Calculations:
According to the question;
⇒ Volume of the cone = (1/3) × (22/7) × 6 × 6 × 21.7
⇒ 818.4 cm3
