    At a school carnival, the diameter of the mat of a trampoline is 10 feet and the diameter of its metal frame is 12 feet. What is the length, in feet, of the metal frame that surrounds the trampoline? Use 3.14 for π and round your answer to the nearest tenth. 15.7 feet 18.9 feet 31.4 feet 37.7 feet

    If you're trying to find the `length` of the metal frame that surrounds the trampoline, that's simply finding the circumference. `circumference = length` So what is the circumference of the circle?

    @geny55 Are you more familiar with this formula \[C = \pi d\] or this formula for the circumference? \[C = 2\pi r\] Mathematically, they are the same, but some people feel more comfortable with one over the other.
