Whoa, that's a lot of damage problems.

Here, we need to find the circumference.

The formula is 3.14 * diameter for Circumference, and the diameter here is 2x the radius = 20 in.

Therefore, the Circumference = 3.14 * 20 in. = 62.8 in.

Now, every time there is a revolution of the tire, the bicycle travels the entire distance of the circumference. I want you to think: Why is that? and reply :D

First solve it for how many inches, then convert to feet. I trust that you can do it wth this information :D

You're Welcome (:

Try the method of substitution. You can put every variable in terms of another variable. For example, you could write u as 3/v, and w as 5/v. Where does that get you?

Yes! "Quarantine" the variable.

Good point.

Sidenote here for the question-asker: This method is called "isolating the variable", and it will pop up for the remainder of your schoolwork, all the way up to middle school and beyond!

o _ O Well, that's just bullyism. Maybe there should be 2 boxes popping up whenever one asks a question (one for the question, and one for their steps that they have taken). Both shall be MANDATORY to fill out. If one doesn't, than one shall get a reply from anyone (to show their work). If one still doesn't, then that question will be removed!
