It quadruples.


What is the cross-sectional area of a 10-in round metal duct?

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.
