The answer is 7.85
First, you divide the diameter by two to get the radius (2.5) and then you multiply by pi(3.14) to get 7.85
I can't see the line very well, but the initial value, also known as the y-intercept, is 1. I would tell you the rate of change but like I said I can't see the line very well, but count across from where the line touches the y axis until you can go up and hit a corner of a square on the grid and the line.. if that makes sense. I hope this helps!
