a piece of wire is in the form of a rectangle whose length is 52cm and breadth is 36cm it is cut at a point and bent in the form of a circle. find the radius of the circle
chttki:
plz send me answer
Area of rectangular wire = 52 * 36 = 1872 cm square
Now the same wire is bent into a circle so the area of circle will be equal to the area of rectangle
Therefore, Area of circle = pi r^2
1872 = 22/7 r^2
1872 * 7/22 = r^2
595 = r^2
24.4 cm = r
