a wheel has a diameter of 18 inches and makes one full turn in 12 seconds and picks up a piece of gym how high off the ground is that piece of gum 18 seconds after the wheel picked it up

  • trig -

    think about it:
    12 seconds the wheel traveled 360 degrees (or returns where it started)

    -so, 12 seconds + 6 seconds (18 seconds total)
    - an additional 6 seconds would mean half of 12 seconds (or half of 360 degrees)
