Answer 1

Answer:

Step-by-step explanation:

Answer 2

As per the data given in the question,

We have to determine the circumference of the circle.

As we know that,

Circumference of circle $=2\Pi r$

So, putting the value of "r" in the given expression,

We will get it as,

$I)\: r = 14\:cm\\Circumference =2\Pi r = 2\times \frac{22}{7}\times 14=88\:cm\\II)\:r = 35\:cm\\Circumference =2\Pi r = 2\times \frac{22}{7}\times 35=220\:cm\\III)\:r = 3.5\:m \\Circumference =2\Pi r = 2\times \frac{22}{7}\times 3.5=22\:m\\IV)\:r = 6\:m\\Circumference =2\Pi r = 2\times \frac{22}{7}\times 6=\frac{264}{7}\:m$

Hence, value of circumference will be following under the given condition.
