Question

Write your question here (Keep it simple and clear to get the best answer)a wire is bent in the shape of a square of side 66cm. if the same wire is looped in the form of a circle,what will be the radius of the circle?

Answer 1

if the sides of the square is 66 cm
then . its perimeter = 4×sides = 4×66 = 264
perimeter of square= circumference of circle
circumference = 2πr
264= 2 × 22/7 × r
44r/7 = 264
44r= 264 × 7
r = 1848/7
r = 264
hence, the radius of the circle is 264 cm

Answer 2

Perimeter of square= Circumference of circle...

$66 \times 4 = 264 = 2\pi \times radius$
radius= 264/2π= 42.01 Cm
