    Lets say pi is 3.14

    The area of a circle is: pi*radius squared

    The radius is half the diameter so it is 5 inches.

    3.14*5 squared 2

    3.14*25

    78.5inches squared

    78.54

    Area of a circle is pi•radius squared

    Radius is half or diameter

    So pi•5 squared which is 78.54
