Radius (r) = 126 cm and π = 22/7
Formula used:
Surface Area of Sphere = 4πr2
Calculations:
Surface Area = 4 × π × r2
⇒ Surface Area = 4 × (22/7) × (126 × 126)
⇒ Surface Area = 4 × (22/7) × 15876
⇒ Surface Area = 4 × 499392/7
⇒ Surface Area = 1997568/7
⇒ Surface Area = 199584 cm2
∴ The correct answer is option (2).
