please i need all steps Mathematic

This is a second year university Mathematics question under the topic of Vector Calculus and Differential Equations. I am so confused. Can anyone please help me out with this question? 

 

(a) Plot the curves in a single graph for  and shade the bounded region only. Then find the area of the bounded region using Area[] function.

(b) Find the length of the entire curve  

Hint: Determine the Domain and Range of the function first. Do not use the built-in ArcLength [ ] function.

(c) Find the surface area obtained by rotating the curve

i. about x axis.

ii.   about y axis.

Please Upload the Mathematica file (.nb) 
Thank you.
