SSC GD Constable 2024 · Question 42 of 75

The radius of a sphere is 4.2 cm. What is the volume of the sphere?

  1. A48.21 cm³
  2. B329.32 cm³
  3. C284.62 cm³
  4. D310.46 cm³Correct

Answer: D. 310.46 cm³

Explanation

The volume of a sphere is given by the formula (4/3)πr³. Substituting r = 4.2 cm: 1. r³ = 4.2 × 4.2 × 4.2 = 74.088. 2. Volume = (4/3) × π × 74.088 = (4/3) × 3.1416 × 74.088 ≈ 310.46 cm³. Thus, the correct answer is 310.46 cm³.
