Question

10. 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

Answer:

perimeter of square=perimeter of circle

for sq

440=4×s

s= 440/4=110m

area=s^2=110^2=12100

similarly

2×22/7×r=440

r=440×7/44=10×7=70m

area =22/7 ×70×70=15400

area circle/area square=15400/12100=14/13
