Question
Perimeter of a square is equal to the perimeter of a
circle that is 704 cm. Find the ratio of the side of the square to the radius of the circle.Solution
ATQ, Let, radius of circle and side of square be ‘r’ cm and ‘a’ cm, respectively. Perimeter of the circle = 2πr 704 = 2 × 22/7 × r 704 × 7/22 × 1/2 = r r = 112 cm Perimeter of the square = 4a 704 = 4a a = 176 cm Required ratio = 176:112 = 11:7
