Oh, dude, you're hitting me with some math at this hour? Alright, so the area of a circle is πr^2, which means you just gotta plug in the radius of 9 inches and do some quick calculations. So, the area of that Pizza would be around 254.47 square inches. But hey, who's really counting when you're about to chow down on some delicious pizza, am I right?

First we have to find the radius: 2*pi*radius = 18*pi Divide both sides by 2*pi to find the radius: radius = 9 inches Area of a circle = pi*radius2 Area = pi*92 = 81pi or 254.4690049 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.
A circle with a radius of 9 inches has a circumference of 56.55 inches and a diameter of 18 inches.
A circle with a radius of 9 feet has an area of 254.47 square feet.
