1.

of side 62find the radius of the circular wire.circular piece of thin wire is converted into a square5cm. If there is no loss or gain in its length,6.25 cm

Answer»

Given side length of square = 6.25 cm

Perimeter of Square = 4*6.25= 25 cm

Circumference of circle = Perimeter of Square

2*pi*r = 252*22/7*r = 25r = 175/44r = 3.97 cm

Therefore, Radius of circular wire is 3.97 cm
