How do we measure crosssectional 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.

No idea. Maybe this was the crosssection of each copper conductor in the cable ?
Or a typo ?

Is it a multistrand cable, i.e. each strand has a CSA of 10 mm˛?

Measuring crosssectional area of a cable
Its a 5core cable actually. Please let me know whether I am calculating crosssectional area of cable correctly? You can help me by telling that what will be diameter of a 6 square mm cable?
Thanx
