Hey all!

I have this problem, and am unable to comprehend what to do, I haven't stumbled upon a question like this before. If anyone can offer assistance, it would be much appreciated.

Consider the two curves $\displaystyle y = 4/x$ and $\displaystyle y = -x+5$

(a) Calculate the area enclosed by the two curves.

(b) Find the volume of the solid generated by rotating the region about the y-axis.

Thanks (Happy)
