Split it up into compound shapes, calculate the areas individually and then add and subtract the relevant quantities.
For instance, the shape in part a can be split up into a quarter circle, a trapezium and a half circle. I have included a diagram that may be of assistance in understanding what I mean but I leave the calculations to you. (They're quite easy when you split the shape up anyway)

Answer: Well, you never actually included any instruction, but, i'm gonna say it is the top right graph.
Step-by-step explanation:
You can deduce that the bottom two are not as the bottom right is going at a consistent rate which makes it linear, the bottom left would be the case if it was an x-intercept of 4. The top left graph is going into the negative x-axis meaning that as x were decreasing, y would be increasing and it is asking for an entire exponential function so you are left with the top right which is in the positive x and y axis and intercepts the y-axis at 4.
