Question
A square has a side length equal to the radius of a circle
whose area is 201.96 m². Calculate the perimeter of the square.Solution
ATQ,
Let the radius of the circle be ‘r’ m
π × r² = 201.96
(22/7) × r² = 201.96
r² = 64
r = 8
Since the side length of the square = radius of the circle = 8 m
Perimeter of the square = 4 × 8 = 32 metres
