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.
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.
A 1.25-inch diameter circle contains 1.227 square inches.
The area of a circle with an 8 inch diameter is approximately 50.27 square inches.
A 4.75-inch diameter circle contains 17.72 square inches.
19.63 square inches are in the area of a 5-inch diameter circle.
The area of a 3-inch diameter circle is about 7.068 square inches.
Area of circle is pi*radius*radius. hence area of 1.5 inch circle is 7.065 square inches.
Area of circle in square inches = pi*radius squared
Area of a circle = pi*radius2 inches
There are 100*pi square inches in a 20 inch diameter circle
70.9 square inches.
That would depend on what you mean by "five inch circle".
A 20-inch diameter circle contains: 314.16 square inches.
