Question 05 (a) 

Let be the region bounded between the curve and the lines Find the volume of the solid obtained by revolving around the yaxis. 
Make sure you understand the problem fully: What is the question asking you to do? Are there specific conditions or constraints that you should take note of? How will you know if your answer is correct from your work only? Can you rephrase the question in your own words in a way that makes sense to you? 
If you are stuck, check the hint below. Consider it for a while. Does it give you a new idea on how to approach the problem? If so, try it! 
Hint 

Recall that by the disk method, the volume of the solid formed by revolving the region bounded by the yaxis and about the yaxis itself is 
Checking a solution serves two purposes: helping you if, after having used the hint, you still are stuck on the problem; or if you have solved the problem and would like to check your work.

Please rate my easiness! It's quick and helps everyone guide their studies. The formula for the volume of the solid obtained by revolving around the yaxis is where is the curve defined by the graph of expressed as a function of
The graph of the region also shows that varies between and so and Hence by the formula
