Question

St bhaiya when bent in the form of a square encloses an area of 121 CM squad the same wire is bent in the form of a circle find the area of the circle

Answer 1

area of a square=121cm^2
so that side of a square=√121
=11cm
.•.perimeter of square=4*a side of square
=4*11
=44cm

•.• same wire is bent in the form of a circle
.•.perimeter of square=perimeter of circle
so that perimeter of circle=44cm

.•.r=44*7/2*22
.•.r=7cm

therefore, area of circle=πr^2
=(22/7)*7*7
=154cm^2 answer
hope this will help you.
