Answer:

$C = 16\pi$

Step-by-step explanation:

Ok, so the equation so find the circumference of a circle is C = 2 $\pi r\\$

So we can fill in the variable for radius as we know it is 8. The equation show know look like this:

$C = 2\pi (8)$

Now we just need to multiply the numbers 2 and 8 together.

$C= 16\pi$

So, because we leave the answer in terms of pi, we're done! :)

In order to determine the correct answer, it would be helpful to set up equations. We do as follows:

Let x = students
y = adults

x + y = 215
.50x + 2y = 250

SOlving simultaneously, we have:

x = 120 students
y = 95 adults

Hope this answers the question. Have a nice day.
