Paul's car can have wheel's ranging from 18-24 inches radius. He has the option of getting a wheel with the diameter of 2 and half feet, 3 and half feet, or 4 and half feet. What size wheel should he purchase? Explain?

18 - 24 radius = 3 to 4 feet in diameter

Thank you Ms.Sue in is that also how you explain it

Yes.

Do you understand it?

I sort of understand it but I'm doing an extended response in I had to explain it in I didn't know how to.

A radius is half the diameter.

18 * 2 = 36 inches = 3 feet

24 * 2 = 48 inches = 4 feet

Oh ok I understand it now thank you so much

You're very welcome.
