A cone has a base diameter of 70 cm and a height of 12 cm. Calculate its volume.
Show answer & explanation
Correct answer: B
Explanation
Base diameter = 70 cm, Height = 12 cm
Volume of the cone = (1/3)πr²h
Volume = (1/3) × (22/7) × 35² × 12
= (1/3) × (22/7) × 1225 × 12
= (1/3) × 22 × 175 × 12
= (1/3) × 46200
= 15400 cm³
