What is the square footage of a 10 inch pipe 10000 feet long?

To find the square footage of a 10-inch pipe that is 10,000 feet long, you first calculate the cross-sectional area. The radius of the pipe is 5 inches (10 inches / 2). The area (A) in square inches can be calculated using the formula (A = \pi r^2), which gives approximately 78.54 square inches. To convert this to square feet, divide by 144 (since there are 144 square inches in a square foot), resulting in about 0.545 square feet. The total surface area of the pipe can then be calculated by multiplying the cross-sectional area by the length in feet, yielding approximately 5,450 square feet.
