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! :)

Express 25km/h into m/s?

Answer:

3600(seconds) can also be expressed as 1(kilometer/hour) = 5/18 (meters/second), which is its simplified form. To convert km/h to m/s, directly multiply the given value of speed by the fraction 5/18.

Step-by-step explanation:

I think that explanation is obvious
