Hello,
I was observing the solution of the following problem below:
Below it says that reducing the cross-sectional area of the wire triples its length. However, according to cross-sectional area equation A=pi*r^2 we observe that reduction of area only leads to reduction of radius .
Is there a mistake or I have some gaps in knowledge regarding above mentioned relationship?
