Question

15. A wire is looped in the form of a circle of radius 35 cm. If it is rebent in the form of a square
what will be the length of each side of the square?
​

Answer 1

Step-by-step explanation:

Since the perimeter of the square wire is equal to the the circumference of the circular wire,

2πr = 4a . . . . eq I

where, r = radius of circular wire = 35 cm

a = side of square = ?

On putting the value if r and in the equation above we get,

2 × 22/7 × 35 = 4 × a [π = 22/7]

(2 × 22/7 × 35) /4 = a

55 cm = a

Hence, the length of each side of the square is 55 cm.
