Find the volume (in cm3, rounded off to 2 decimal places) of a right circular cone of diameter 12 cm and height 5 cm. [Use π = ]
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 188.57.
Diameter = 12 cm
Radius (r) = 12 cm / 2 = 6 cm
Volume of cone = (1/3)πr2h where r is the radius and h is the height.
= (1/3) × (22/7) × (6)2 × 5
= 188.5714... cm3
= 188.57 cm3
Therefore, the volume of the cone is 188.57 cm3.
