Answer / aravind

Area=3.14*r^2

r=8.74mm

Answer / rajesh palande

When we say that cable rating is 240 sq mm the user knows
that the area of the conductor is 240 square mm. Hence user
can determine the amount of current that cable can carry.
Calculate the dimension of circle which has a area of 240
sq mm and you get the answere about dia size.

Answer / mateen

When you got the cross section aria then you can calculate
the current currying ampere by knowing the materials
Resistance

Answer / sumit tomar

it is bcoj the cable diameter is decided wby the amount of
current it hav to bear.....thus the conductor is choosen
according to its dia size...
