<u>Option </u><u>C </u><u>-</u><u> </u><u>7</u><u>2</u><u>.</u><u>2</u><u>2</u><u> </u><u>units </u>is the correct answer .
Step-by-step explanation:
In this question we are given with <u>diameter</u><u> of</u><u> circle</u><u> </u><u>that </u><u>is </u><u>2</u><u>3</u><u> </u><u>units </u><u>and </u><u>value </u><u>of </u><u>π </u><u>as </u><u>3.</u><u>1</u><u>4</u><u> </u><u>.</u><u> </u><u> </u> And We are asked to find the<u> </u><u>circumference</u><u> of</u><u> circle</u><u>. </u>
We know that ,
<u>Where </u><u>,</u>
π = <u>3.</u><u>1</u><u>4</u>
d = <u>diameter</u><u> </u><u>of</u><u> </u><u>circle</u>
