A 12-inch circle has an area of about 113.1 square inches.
36 pi squinches
The area of a circle is calculated using the formula A = πr^2, where r is the radius of the circle. For a 12-inch circle, the radius is half of the diameter, so the radius is 6 inches. Therefore, the area of the 12-inch circle is A = π(6)^2 = 36π square inches. Similarly, for a 9-inch circle, the radius is 4.5 inches, so the area of the 9-inch circle is A = π(4.5)^2 = 20.25π square inches.

36 pi squinches
Area of the circle: pi*6 squared = 36*pi square inches
The area of a circle is calculated using the formula A = πr^2, where r is the radius of the circle. For a 12-inch circle, the radius is half of the diameter, so the radius is 6 inches. Therefore, the area of the 12-inch circle is A = π(6)^2 = 36π square inches. Similarly, for a 9-inch circle, the radius is 4.5 inches, so the area of the 9-inch circle is A = π(4.5)^2 = 20.25π 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.
