Diameter of the sphere = 98 cm
Radius (r) = Diameter ÷ 2 = 98 ÷ 2 = 49 cm
Formula used:
Surface Area of a Sphere = 4 × π × r2
Where, r = radius
Calculations:
Surface Area = 4 × π × r2
⇒ Surface Area = 4 × 22/7 × 492
⇒ Surface Area = 4 × 22/7 × 2401
⇒ Surface Area = 30,184 cm2
∴ The correct answer is option (4).
