The area of a circle-sector is:

Use that for each small sector of your areas, add them up, then change the number of elements in theta and repeat.

You appear to be very new to matlab. Therefore I suggest that you work through the on-ramp tutorials/course:on-ramp.
Then have a browse through the demos and the help.
For integration the simplest ways are: trapz and integral.
