Answer:
c
Step-by-step explanation:
There can be more then 1 mode.
Sometimes, there is not even a mode.....and other times, there is 1 mode.
If the radius is 7 and 3/4, then the answer is 48.6947
c=2pie•r
plug in 7 and 3/4 for r and get 48.6947
The midpoint is calculated by averaging the coordinates of its endpoints:

Now we can use the usual distance formula to get the length of SM:
