Claire has a hot tub with a diameter of 7 feet. She wants to purchase a cover to protect the hot tub. What is the area

of the cover? Use pi = 3.14 and round the answer to the nearest square foot.

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.

I believe it is 38
