Answer 2

In context to questions asked,

We have to determine the value of r

As per questions,

We have,

$2 \times \Pi \times r = 6$

As we know that,

Value of pi is equal to 22/7.

So, after putting the value we will get it as,

$2 \times \Pi \times r = 6 \\ = > 2 \times \frac{22}{7} \times r = 6 \\ = > r = \frac{6 \times 7}{22 \times 2} \\ = > r = \frac{42}{44} \\ = > r = \frac{21}{22}$

Hence, value of r will be 21/22
