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!
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 in square inches = pi*radius squared
Area of circle is pi*radius*radius. hence area of 1.5 inch circle is 7.065 square inches.
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.
