Question

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)

Answer 1

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.
