    Length of ribbon = 40.86 inches

    Step-by-step explanation:

    Length of the ribbon = circumference of the dish = πD

    D = diameter = 13 inches

    Length of ribbon = 22/7 x 13 = 40.857143 inches

    40.9 inches

    Step-by-step explanation:

    The question say that:

    Pam served her apple pie on a 13 inch diameter dish. She wanted to tie a ribbon around the dish to make it a little more festive. How long does the ribbon need to be in order to fit around the dish

    First and foremost, we need to know what this question is all about.

    The dish is obviously a circle in terms of its shape and the dish has a diameter of of 13 inch.

    The circumference of a circle is 2 pi * radius

    And we all know that how long a circle is it's circumference.

    Diameter is twice of a radius so if the diameter is 13 inch, then the radius will be 13/2 = 6.5 inch

    Circumference = 2 * 22/7 * 6.5 = 40.857 inches.

    Therefore, the length of the ribbon to be tied round the plate is 40.9 inches.
