if the diameter of a circle is one
foot, then the radius of the circle is how many inches?

  • 4gr math -

    A radius is half of the diameter.

    1 foot = 12 inches

    How long do you think the radius is?

  • 4gr math -

    13

  • 4gr math -

    13 is not half of 12.

    Divide 12 by 2.

  • 4gr math -

    Right. The radius is 6 inches.
