formula for total surface area for cylinder, please , need formula only. please
Develop formula for surface area of cylinder:

Area = (2(pi)r2) + (2(pi)rh)

Thank you very much sir

I picture solutions in my mind and I see a cylinder as a sheet of paper wrapped around into a circle. Open the paper back up and the surface is length X width.

to be clear:
Area_{cylinder}=2(\text{area of the circular end}) + (\text{area of the side}) = 2\pi r^2 + 2\pi r h
