Question

if a wire of 440 M length is the molded in the form of circle and and a square 10 by 10 find the ratio of the area of the circle to that a square

Answer 1

hello frnd!

here's ur answer...

circumference of circle=perimeter of square

the length of the wire is 440m, therefore the circumference of the circle is 440m

2πr=440m

2×22/7×r=440m

44/7×r=440m

r=440/1×7/44

r=10×7

r=70m

area of the circumference of the circle=πr²

=22/7×70×70

=22×10×70

=15400m²

perimeter of square is also 440m

side×4=440m

side=440/4

side=110m

area of the square=side×side

=110×110

=12100m²

area of circle is more by=15400-12100

=3300m²

hope this helps..!

Answer 2

circumference of circle=2πr
440=2πr
440x7/22x2=r
r=70m
area of circle =πr^2
=22/7x70x70
=22x70x10
=15400m square
area of square=10mx10m
=100msquare
their ratio =area of circle /area of square
= 15400m square/100 m square
=154:1

I hope this answer is correct.
