Question

A wire when bent in the form of a square encloses an area of 196 cm square if the same wire is bent to form a circle find the area of the circle

Answer 1

p of square = 196 cm

p of square = circumference of circle

hence circumference of circle = 196cm

2πr = 196

2 * 22/7 * r = 196

44r= 1372

r= 1372/44

r= 31.2 (approx)

area= πr^2

22/7 * 31.2 * 31.2

3059.3 cm^2 (approx)
