A conductor with a diameter of 100 mils has an area of?

To calculate the area of a conductor with a diameter of 100 mils, first convert the diameter to radius by dividing by 2, which gives a radius of 50 mils. The area ( A ) of a circle is calculated using the formula ( A = \pi r^2 ). Therefore, the area is ( A = \pi \times (50 \text{ mils})^2 ), which equals approximately 7854 mils².
