How to calculate weight of aluminium circle?

To calculate the weight of an aluminium circle, you need to know its diameter, thickness, and density. The density of aluminium is approximately 2.7 grams per cubic centimeter (g/cm³) or 2700 kilograms per cubic meter (kg/m³).

The formula for calculating the weight of an aluminium circle is:

Weight = Density x Volume

Volume of a circle can be calculated using the formula:

Volume = π x (diameter/2)² x thickness

where π (pi) is a mathematical constant equal to approximately 3.1416.

Therefore, the formula for calculating the weight of an aluminium circle is:

Weight = Density x π x (diameter/2)² x thickness

Suppose we have an aluminum circle with a diameter of 50 cm and a thickness of 1 mm. To calculate the weight of this circle sheet, we can use the following formula:

Weight = 2.7 g/cm³ x π x (50 cm/2)² x 0.1 cm = 530.15 grams

Therefore, an aluminum circle with a diameter of 50 cm and a thickness of 1 mm weighs 530.15 grams, which is about 0.5 kg.

Note that this formula gives you the weight of the aluminum circle in grams. If you want the weight in other units, such as pounds or ounces, you will need to convert the weight accordingly.
