Question

a circular piece of wire is converted into a rectangle of with 2.75 cm and length 3.25 if there is no loss or gain and its length then the radius of the circular wire is​

Answer 1

Answer:

Step-by-step explanation:

length stays the same

radius= 2*pi/2.7

Answer 2

Answer:

1.91 cm

Step-by-step explanation:

length of rectangle=3.25 cm

breadth (width) of the rectangle=2.75c m

per. of rec.(rectangle)=2(L+B)

                                   =2(3.25+2.75)

                                   =2*6

                                   =12 cm

as a circular piece of wire is converted into a rectangle of with 2.75 cm and length 3.25 if there is no loss or gain and its length then the circumference of the circle and perimeter of the rectangle will be the same.

therefore-circumference=12 cm

              radius=?

circumference=2πr(π=3.14)

12=2*3.14*r

2*3.14*R=12

3.14*r=12/2

3.14*r=6

r=6/3.14

r=1.91
