The area of the cross section for this case is a circle.
Therefore, the area is given by:
[tex]A = \pi * r ^ 2
[/tex]
Where,
r: radius of the circle
Substituting values we have:
[tex]A = 3.14159 * (25/2) ^ 2
A = 490.8734375 mm ^ 2[/tex]
Rounding to two decimal places:
[tex]A = 490.87 mm ^ 2
[/tex]
Answer:
The cross-sectional area of a conductor in millimeters squared is:
A = 490.87 mm ^ 2
