Hello,
The formula for finding the circumference of a circle is 2 \pi r where r is the radius. SO we can plug 4 in for r in this formula because 4 is the radius:2 \pi 4=8 \pi. We are told to use 3.14 for \pi so we get 8(3.14)=25.12. Therefore, the circumference is 25.12 meters.

We factor the equation to get:

-(x-25)^2+361

In the form a(x-h)^2+k, the vertex is (h, k), so the vertex is (25, 361).  This means that the studio makes the most profit from selling 25 memberships, and thus makes 361 dollars.

B.  The x-intercepts are the values of x for which f(x) is 0.  This equation can be factored as (-a+6)(a-44)=0, with solutions 6 and 44.  Therefore, by selling either 6 memberships or 44 memberships, the studio breaks even, neither making nor losing money.
