Answer:
31.41592...
Step-by-step explanation:
If the radius of the circle is 10 inches, the circle's circumference is 31.4 because you calculate circumference as follows:
x = r * pi (3.1415926535)
37.50 rounded to the nearest tenth is 37.5
So you need to get your slope formed then rise over run and calculate your graph. Y=Mx+b
