    The options are unclear but the answer is 8^2π square feet or 64π sqfeet

    Explanation:

    Area of a circle is denoted by: πr^2 where r is the radius of the circle.

    In this question, the diameter was given. The diameter of a circle is twice the radius. Therefore, in order to get the radius, we divide the diameter by 2 i. e. r = d/2

    = 16/2 = 8 feet.

    Thus, the radius = 8 feet.

    Hence, Area of a circle = πr^2

    = π * 8^2

    = 64π or 8^2π sqfeet.
