Question

the steel wire when bent in the form of square encloses the area 121 sq.cm. If the same wire is bent into the form of circle. find the area of circle

Answer 1

area of square = a square

a^2=121

a=11 cm

perimeter of square of 4a = 44 cm

circumference of circle formed = perimeter of square

44= 2 × pi×r

22= 22/7×r

r=7cm

area of circle = pi × r^2

22/7×7×7=154 cm sq.
