I am supposed to use integration to solve ,, for surface area \[s=2\pi \int\limits_{a}^{b} X dL\] but I guess we need to edit this equation to calculate the lateral surface area but I don't know what is it??

The area of the curved (lateral) surface of a cone = πrl I guess I'll remove the 2 from the equation right ? in order to calculate it

I calculated it and figured out it is the same I misunderstood something Thank you the 2 pi in the equation is the revolution of the area it means it will revolve one complete revolution THANKS
