Well, isn't that just a happy little question! To find the number of square inches in a circle, we use the formula A = πr^2. Since the circle has a radius of 6 inches, we square that (6^2 = 36) and multiply by π to get approximately 113.1 square inches. Just imagine all the lovely colors you could paint in that space!

Oh, dude, you're hitting me with the math questions! So, like, the area of a circle is πr^2, where r is the radius. Since the radius is half the diameter, which is 6 inches, the radius is 3 inches. Plug that into the formula, and you get 3.14 x 3 x 3 = 28.26 square inches. So, like, there are 28.26 square inches in a 6-inch circle.
The area of a circle is calculated using the formula A = πr^2, where A is the area and r is the radius. In this case, the radius is half of the diameter, so it is 3 inches. Plugging this into the formula, we get A = π(3)^2 = 9π square inches. Approximating π to 3.14, the area is approximately 28.26 square inches.
A 1.25-inch diameter circle contains 1.227 square inches.
A 4.75-inch diameter circle contains 17.72 square inches.
Area of circle in square inches = pi*radius squared
Area of a circle = pi*radius2 inches
A 20-inch diameter circle contains: 314.16 square inches.
