Not the solution but an idea of how to approach such questions.
There are eight of the shaded area in the second problem, so work one out and multiply by 8.

Ok this is evil, but alot of student wont be able to see this. Q4 and Q5 are probably related if you can see it. Since 5 circles are identical so you take area of a circle minus the area of shaded region in question 4.

On a side note, students cant really tell q4 and q5 are related, so I would say it is pretty unfair for them.
