1.) Trevor needs a new bicycle tire. His tire has a circumference of about 112inches. What is the diameter of his tire? (round to the nearest tenth place)

1) Take the equation of the circumference of a circle (C = 2*pi*r)

2) Plug in what you have. (112 = 2*pi*r)

3) Divide each side by pi*r. (112 / 2*pi=r)

4) Solve this equation ... (You get the radius by multiplying the answer by 2)

The diameter is 351.86 inches.
