Question
The surface area of a sphere is
given as (12474/25) cm². Calculate the diameter of the sphere. (Use π = 22/7)Solution
ATQ,
Let the radius of the sphere be 'r' cm. Surface area of sphere = 4 × π × r2 ATQ; 
r = 63/10 = 6.3 {Since, radius cannot be negative} So, diameter of the sphere = 6.3 × 2 = 12.6 cm
