  1. C = pi * d
    C = 3.14 * 2.4
    C = ______ feet

    Multiply the circumference by 10.

  2. C= 75.36 ft. But may I ask how you got 2.4 which you multiplied by 3.14?

  3. The radius is half the diameter.

    The circumference can't be 75 feet. 2 times 3 is normally 6 -- so the radius must be 7.536 feet.

  4. My mistake. Sorry.
