The area of a circle is calculated using the formula A = πr^2, where A is the area and r is the radius of the circle. Since the diameter of the circle is 12 inches, the radius would be half of that, which is 6 inches. Converting inches to feet (1 foot = 12 inches), the radius would be 0.5 feet. Plugging this into the formula, the area of a 12-inch circle would be approximately 0.785 square feet.

There's no way to express area in feet - it needs to be square feet.
A circle of radius 12" has an area of pi sq. ft. ~= 3.141 sq. ft.
A circle of diameter 12" has area pi/4 sq ft ~= 3/4 sq. ft.
Area of a 12-inch circle: 113.1 square inches.Area of a 16-inch circle: 201.1 square inches.
The approximate area of a circle with a 12-inch diameter is: 113 square inches.
The circumference of a circle is given by Circumference = pi x diameter. The area of a circle is given by Area = pi/4 x diameter2. Thus for a circle with circumference c = 12 in. The area will equal a = 11.459 in2.
I assume 12 is diameter. If so 12/2 is radius of 6in. 6x6xpi is 113.1squared inches
Area of a circle = (1/2 x diameter)2 x piArea of a 24 inch diameter circle:(12 inches)2 x 3.1416 = 144 square inches x 3.1416 = 452.4 square inches
