Length and breadth of a piece of rectangular wire are 18 cm and 15 cm. It is bent into the shape of a circle . find the diametre of the circle

Open in App

Solution

Perimeter of rectangular wire = circumference of circle

2(l+B) =2 πr

33 = 22/7 r (value of pi is approximately 22/7 )

r = 7*33/22

r = 21/2

diameter = 2r= 21cm
