Q: A curve C is defined by the following pair of parametric equations:

$\displaystyle x = 1 + t^2$ and $\displaystyle y = \displaystyle{\frac{3 - t}{2+ t}}$ for 2 \1oq t \1oq 4. The region R is bounded by C, the x-axis and the lines x = 5 and x = 17.

a) Find the exact area of the region R.

b) Find V, the volume of solid generated when R is rotated through $\displaystyle 2\pi$ about the x-axis.

Please help! This is urgent! If possible, please include working and answers so I can compare with what I have done...Thank you very much!
