The area of a circle with a diameter of 9 inches is: 63.62 square inches.
To find the area in square feet, first convert the dimensions to feet. 9 feet 19 inches is equivalent to 9 feet + 1 foot 7 inches, which totals 10 feet 7 inches or 10.583 feet. 9 feet 3 inches is 9.25 feet. The area is calculated as 10.583 feet x 9.25 feet, which equals approximately 97.9 square feet.
