Question

A wire which was bent in the shape of the square, is now given the shape of a circle. What will be the ratio of the areas covered by them?​

Answer 1

$\large \underline{ \bf \red{Solution:-}}$

=> The area of the circle = 3850 sq cm.

=> The radius of the circle = [3850*7/22]^0.5 =35 cm.

=> The circumference of the circle = 35*2*22/7 = 220 cm.

=> Perimeter of the square = 220 cm.

=> Side of the square = 220/4 = 55 cm.

=> Area of the square = 55^2 = 3025 sq cm.
