Correct Answer - Option 1 : 1643 cm
3
Given:
The radius of the cone 3.5 cm
The vertical height of the cone 9 cm
Concept:
The volume of the cone = (1/3) × (π × r2 × h)
Calculation:
⇒ Volume of the cone = (1/3) × (22/7) × (3.5 × 3.5 × 9) = 115.5
⇒ Volume of the hemispherical portion of ice cream = (2/3) × (π × r3)
⇒ (2/3) × (22/7) × (93) = 1527.42 ≈ 1527.5
⇒ Total volume of icecream = 115.5 + 1527.5 = 1643
∴ The required result will be 1643 cm3.
