Question
Given that the surface area of a sphere is 201.06 cm²,
calculate its volume.Solution
ATQ,
Surface area of sphere = 4 × π × radius²
So, 4 × (22/7) × radius² = 201.06
Or, radius² = 16.03
Or, radius = ± 4.0
But radius cannot be negative. So, radius = 4.0 cm
Volume of sphere = (4/3) × π × radius³
= (4/3) × (22/7) × 4.0³
= 268.19 cm³
