Answer:
2r = 22/π , as we know π is an irrational number and can not be expressed as a common fraction, and it's decimal form never ends as well as it never comes even into a permanent repeating pattern. But if we use fraction 22/7 as the value of π, which is very commonly used — then
2r = 22/(22/7) (approx.) = 7 cm (approx.)
