Answer:
127 square ft

Step-by-step explanation:
The formula to find the area of a circle with a know circumference is: C^2/4 π.

40^2 is 1600 and 4 times pi is 12.56. Divide 1600 by the 12.56 and you will get your area of 127.39. The answer is 127 square ft after rounding to the nearest square foot.
