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.

What is heat transfered through a metal spoon called?
Heat transfer through a metal spoon is called conduction. This occurs as heat travels through the metal by the collision of particles within the material. The metal spoon acts as a conductor, allowing the heat to move from a higher temperature area to a lower temperature area.
What would increase the amount of heat the metal radiates to the air?
Increasing the temperature of the metal, increasing the surface area of the metal, and improving the thermal conductivity of the metal would all increase the amount of heat the metal radiates to the air.
Does a short thick metal wire or a long narrow metal wire have more resistance?
A long narrow metal wire would have more resistance compared to a short thick metal wire. Resistance is directly proportional to the length of the wire and inversely proportional to the cross-sectional area, so a longer wire with a smaller cross-sectional area will have higher resistance.
Why do objects that are round fall faster than objects that are flat?
Objects that are round fall faster than objects that are flat because they experience less air resistance. The round shape of an object reduces the surface area in contact with the air, allowing it to move through the air more smoothly and with less drag. This results in round objects falling quicker than flat objects.
Why the Microwave signal can not pass when Metal Reed Screen in perpendicular direction?
Metal screens act as barriers to microwave signals because the metal has a high conductivity that reflects and absorbs the microwaves, preventing them from passing through. When the metal screen is oriented perpendicular to the direction of the microwave signal, it creates a larger surface area for reflection and absorption, effectively blocking the signal from passing through.

Find the area of a circle when the circumference is 10in?
The area of a circle when the circumference is 10 inches is: 7.96 square inches.
What is the area of 14 in and 20 in and 10 in and 12 in?
Area = 14in x 20in = 280in2 Area = 10in x 12in = 120in2
A square and a triangle have equal areas and a side of the square is 10 inches and the base of the triangle is 10 inches then what is the height of the triangle?
Area triangle = 1/2 base x height Area square = length x width = 10in x 10in = 100sq in. Area triangle = area square Therefore: 1/2 x 10in x height = 100sq in height = 100 sq in x 2 / 10 in = 20 in
What is the square feet of 7ft 10in by 6ft 10in?
Multiply the two dimensions to get the area. In this case the calculation gives you 7,708 square inches, which divided by 144 gives you 53.53 square feet.
What is the area of a rectangle with sides of 3 in by 10 in?
The area would be 30 square inches. To figure that out, you multiply 3in x 10in. You're Welcome. :)
What is the cross sectional area of a 10 inch metal round duct?
Cross-sectional area = pi*radius2
Area of a parallelogram the base is 10 and the height is 24in?
This is the exact same answer as the area of a 10in x 24in rectangle. Essentially, you are multiplying the base and height of a rectangle to get its area, too.
