Question
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):Solution
Height =7cm, diameter =12cm r =6cm Volume of the cone = (1/3) × π × r² × h  = (1/3) × π × 62 × 7 ⇒ (1/3) × (22/7) x 36 x 7 ⇒ 264 cm³ The volume of the cone is 264 cm³.
