How do we measure cross-sectional area of a cable (obviously circular)? For example, diameter of a cable as measured from vernier caliper was 19.5 mm. If we apply A = pi(3.14) r2, answer is 298.49 mm square but tag on said cable is showing Area = 10mm square? Please explain.
Its a 5-core cable actually. Please let me know whether I am calculating cross-sectional area of cable correctly? You can help me by telling that what will be diameter of a 6 square mm cable? Thanx
