How many square inches in a 6 inch roubd pipe?
To find the area of a 6-inch round pipe, you can use the formula for the area of a circle, A = πr². The radius (r) of a 6-inch pipe is 3 inches. Therefore, the area is A = π(3²) = π(9) ≈ 28.27 square inches.

What is the area of a sheet of 9-inch by 12-inch paper?
The area of a sheet of paper can be calculated by multiplying its length by its width. For a 9-inch by 12-inch sheet, the area is 9 inches × 12 inches, which equals 108 square inches.
What is the area of a 12 inch and a 9 inch circle?
If you are talking about 9 and 12 inch diameter, then divide both by 2 to get the radius. The area of a circle is pi (3.1415 is good for most calculations) multiplied by the square of the radius. So for the 12 inch circle, the radius is 6. The square of the radius is 36, and multiplying this by pi gives approximately 113.1 square inches. Now the 9 inch circle has a radius of 9/2 or 4.5. Squaring this we get 20.25, which multiplied by pi is approximately 63.6 square inches. If 9 and 12 were already the radius in the problem, just don't divide by 2 since you already have the radius.
