Question

if a wire of 440 m length is moulded in the form of a circle and a square turn by turn, find the ratio of the area of the circle to that of square.

Answer 1

perimeter of circle=2.pi.r
440m=2 x 22/7 x r
r=70m
area of circle =pi.r^2=22/7 x 70 x 70
=15400m^2

perimeter of square=4 x side length
440=4 x side length
side length=110m
area of square=(110m)^2=12100
now question ask
area of circle/area of square=15400/12100
=14/11

Answer 2

hence the area =14/11
