Answer:
The answer is A. 17π
Step-by-step explanation:
In order to get this answer I looked at the formula for the circumference of a circle and the formula is c = 2πr (c being circumference, r being radius, π being pie) So if the bigger circle's circumference is 68π then you need to divide 68 by 2 to figure out the radius.
So 68/2=34 and the radius of the smaller circle is 1/4 of 34 which is 8.5.
Then you multiply the radius (8.5) by 2 to get 17π for your final answer.
So happy to help! Please let me know if I was wrong or right! :)
