How to curve a cylinder I am new to blender and I want to curve a cylinder like in the image below
Any help will be appreciated

Select the Spin tool:

Rotate the edge, use Ctrl to constrain to 10° by 10°, tweak the Operator box parameters if necessary:

You could also use a Curve modifier but it will be a bit slower
