    Answer: Area of circular plate is 36.5 square inches

    Step-by-step explanation:

    The formula for determining the circumference of a circle is expressed as

    Circumference = 2πr

    Where

    r represents the radius of the circle.

    π is a constant whose value is 3.14

    From the information given,

    Circumference of circular plate = 21.4 inches. Therefore

    2 * 3.14 * r = 21.4

    6.28r = 21.4

    r = 21.4/6.28

    r = 3.41 inches

    The formula for determining the area of a circle is expressed as

    Area = πr²

    Area of circular plate = 3.14 * 3.41² = 36.5 square inches
