How do we convert mm diameter into mm2 ? What is the formula used for this converaion?
Oh, I see. Can you give me an example of how this formula works?
Of course! Let's say we have a wire with a diameter of 5 mm. To find the area, we first need to find the radius. The radius would be 2.5 mm (half of the diameter). Then we can use the formula A=πr^2, which gives us an area of 19.63 mm2 (using 3.14 for π).
