OK got it. but I am unable to solve this type of questions
please explain me this topic with few examples
the graph you sent me is not given in study material
if you have any material related to the topic "SURFACE AREA AND VOLUME BY DOUBLE INTEGRAL " then please please share with me
These type of questions are difficult to visualize in first attempt. So just keep continuing practice. Use '3D Calculator' app. It will help you in 3d graphs. And you can see lectures based on this portion on youtube too
You can also follow book Thomas Calculus for Calculus part.
