Answer:The area  of the cover for the hot tub must be:38 square feet.Step-by-step explanation:First, you must understand that since a hydromassage tub is mentioned and the diameter, it is assimilated that it is round in its upper part, which is why the formula is used to find the area of a circle: Area of a circle = pi * radius ^ 2 (you must know that the radius is half the diameter) Since the diameter is mentioned, it can be replaced in the formula: Area of a circle = 3.14 * (3.5 feet) ^ 2 Area of a circle = 38,465 square feet. Approximately 38 square feet.
