A wire is in the form of square with side 44 cm. It is bent to form a circle. What is the radius of the circle?
Answer & explanation
Correct answer: option 1
The length of the wire is constant,
Perimeter of the square = circumference of circle
4 x (side) = 2$\pi$ r
⇒ 4 x 44 = 2 x $\frac{22}{7}$ x radius
⇒ radius = 28 cm
