Trevor needs a new bicycle tire. his tire has a circumference of 112 inches. what is the diameter of his tire.?

First, you take the equation of the circumference of a circle which is: C=2πr
Next, you would plug in what you have.  So right now you have the circumference. So 112=2πr.
Last what you would do is divide each side by πr so you would end up getting:
112/2π=r
By doing that equation, you would get the radius so you would just multiply your answer by 2.

The diameter is 351.86 inches

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
