Hai i have a doubt in the statement 1. we can rephrase the statement 1 as

circumference/diameter=pi*d/d since pi=22/7.

pi*d/d=3*1/1,so diameter is 1 and radius is 1/2. sufficient to answer the question.

Please correct me if i am wrong.

It's incorrect.

The ratio of the circumference of the circle D to the diameter of the circle D is always 22/7 :1

You can try calculating that ratio for different values of r.
