A) integral just measures the area under the function. So find the area under your top curve (parabola) and subtract it by the bottom curve (the line). The bounds are the intersections of your functions.
B) The are of the rotation can be calculated with discs/ washers. To do this, use the formula of the circle with your radius equaling the top curve and then subtract it from the bottom volume bounded by the rotation of the bottom curve.
C) now split your region into two and use $y$ as your variable instead of $x$.
I will be more than happy to expand on my answer if you show your work and tell us where you are stuck/unsure.
