This is for economics. I have the figures for goods credit and goods debit. Then services debit and services credit.
I can't remember the formula, if there is one..
So I missed out a couple of weeks on maths and missed out quite a bit :uhoh:
I don't understand what is this "In" thing in the questions. I only have formulas with either "log" and "x", "d", "v" signs.

These questions are the ones I'm stuck on. I don't need all of them...
I attempted the first question and got like halfway but I don't know how to do find volumes of semicircles in integration.
There are 2 questions I'm stuck on for the first image its on the right question b) and 16. Sorry for the bad quality
Find the shaded area is rotated around the y-axis. Find the volume of the solid formed.
This is the question. I don't understand how I keep getting this wrong! I used the formulas in the pic
