Question

a wire in the shape of a square of side 11 metre is bent into the shape of a circle find the area of the circle​

Answer 1

Answer:

area=154cm^2

Step-by-step explanation:

lt is given that wire was earlier square and it was now bent into a circle this shows that circle and Square will have equal perimeter

therefore,

4×side=2πr

4×11=2×22÷7×r

so,r=7cm

area of circle is=πr^2 22÷7×7

area=154cm^2

Answer 2

Step-by-step explanation:

side of a square = 11 m

perimeter of the square = 11*4=44m

In the form of a circle, it's circumference = 44m

Radius of circle=

Circumference=2πr

44=2*22/7*r

44=44/7*r

r=44*7/44

r=7m

Area of circle =πr^2

=22/7*7*7=154m Answer
