Kartik Jambur from Delhi Public School East, Bengaluru

Class : Class 8

Answer is C. Circumference of the circle will be equal to l (the wire forms the circle) 2 * 22/7 * r = l , r = l/44/7 Area = 22/7 * r * r = 22/7 * l/44/7 * l/44/7 = l*l/4*44/7 Therefore radius : area = l/44/7 : l*l/4*44/7 = 2 : l Hope it helped!
