Question

If a wire of 440 M length is moulded in the form of a circle and Square turn-by-turn find the ratio of the area of the circle of that of square

Answer 1

length of wire= 440m

circumference of the circle= 440m

circumference=2*22/7*r

• 440 = 2*22/7*r
• 440 * 7 / 44=r         {sending the known values from the rhs to the lhs}
• 10*7=r
• r= 70 m

Hence area of circle= 22/7*r*r

area=15400 m square

now area of the square

perimeter = 4*side

side= 440/4

side= 110 m

area= side * side

area= 110*110

area=12100 m square

area of circle/area of square

15400/12100

= 154/121

Hence ratio is 154:121

You can divide it further if u can

Hope this helps! Plz vote! :)))
