A wire is bent in the form of a circle of radius 28 cm. The same wire is then re-bent in the form of a square. The side of the square is
A22 cm
B44 cm
C88 cm
D14 cm
Answer & Solution
Correct answer: B. 44 cm
1. Wire length = circumference = 2 × (22/7) × 28 = 176 cm.
2. Perimeter of square = 4 × side = 176; side = 44 cm.
3. Hence 44 cm.
