What is the cross sectional area of the 4 inch pipe?

Answer 1

The cross-sectional area of a pipe can be calculated using the formula for the area of a circle, A = πr^2, where r is the radius of the pipe. Since the diameter of the pipe is given as 4 inches, the radius would be half of the diameter, so r = 2 inches. Plugging this value into the formula, we get A = π(2)^2 = 4π square inches. Therefore, the cross-sectional area of the 4-inch pipe is 4π square inches.

Answer 2

Oh, dude, the cross-sectional area of a 4-inch pipe can be calculated using the formula for the area of a circle, which is πr^2. So, for a 4-inch pipe, you just need to divide the diameter (4 inches) by 2 to get the radius (2 inches), then plug it into the formula. Like, it's just basic math, nothing too crazy.

Answer 3

Well, isn't that a happy little question! To find the cross-sectional area of a pipe, you can use the formula for the area of a circle, which is A = πr^2. Since the diameter of the pipe is 4 inches, the radius would be half of that, which is 2 inches. Plugging that into the formula, the cross-sectional area of the 4 inch pipe would be approximately 12.57 square inches.

Answer 4

A "4-inch pipe" means it has a diameter of 4 inches, which makes the radius 2 inches.

Did you ever see the formula pi*r^2 for area of circle?

The answer is 4pi where pi=3.1416

Answer 5

12.65
