Question

a wire is in the shape of a rectangle.its length is 40 cm and breathe is 22 cm. if the same wire is rebent the shape of square and then into a circle. find : the radius of circle​

Answer 1

Perimeter of rectangle(P)=2(l+b)

P=2(40+22)

P=2(62)

P=124cm

Circumfrence of circle=Perimeter of rectangle

134=2pi r

134*7/22*7=r

r=19.72cm

Answer 2

Answer:

Step-by-step explanation:

P(rectangle) = 2[l+b]

    = 2 [ 40 + 22]

    = 2 x 62

    = 124cm

    = P(circle)

2 x 22 x r/7 = 124

44r = 868

r = 19.72cm
