The answer to this question is D: 2. To solve this, you must work backwards, and what's the oppsite of addition? Subtraction! Take 2.34, your final answer, and subtract .34 from it, and you end up with 2! I hope this helped! Could I possible get brainliest?
23 divided by 2 is 11.5 so that is the radius. Then you multiply the radius by pi. Or you can do 11.5 x 11.5 if you are trying to find the solution without pi.
