Answer 2

Answer:

69.12mm

Step-by-step explanation:

Let r be the radius of the circle. Its diameter is 2r and circumference is 2πr. Here

2πr = 22 cm (given)

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.)
