An equilateral 1 inch triangle is a plane figure and it does not have a cross-sectional area in any meaningful sense, just an area. Its area is 0.43 = sqrt(3)/4 square inches.
It is approx 0.003068 square inches.
Usually it means a piece of wood/lumber that has a cross-sectional area of 4 square inches, meaning that the cross section is a square of 2 inch side.
Cross-sectional area = pi*radius2

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.
The cross-sectional area of a 10-inch round metal duct can be calculated using the formula for the area of a circle: A = πr^2, where r is the radius of the duct. For a 10-inch round duct, the radius would be half of the diameter (10 inches), so the radius is 5 inches. Plugging in this value into the formula gives A = π*5^2 = 25π square inches, or approximately 78.5 square inches.

The question can't be answered as asked. PSI (pounds per square inch) is a measure of pressure (or force) over a given surface area, but without knowing the surface area in question, the psi can't be calculated. However, it might help to understand it better by considering that a 1000 pound weight that is spread evenly over a surface area of 1000 square inches will only have a psi of 1. On the other hand, if you take that same 1000 pound weight and put it on a hand truck with two wheels, each wheel having a surface area (the area of wheel in contact with the ground) of 4 square inches, the area beneath each wheel will have a force (or pressure) of 125 psi being placed on it. Hope that helps.
