Question
A square has its side length equal to the radius of a
circle. If the circle's area is 962.5 m², find the perimeter of the square.Solution
ATQ,
Let the radius of the circle be ‘r’ m
π × r² = 962.5
(22/7) × r² = 962.5
r² = 306.25
r = 17.5
Since the side length of the square = radius of the circle = 17.5 m
Perimeter of the square = 4 × 17.5 = 70 metres
