hi
I want to find the area inside the circle r=2, with x>0 and y>1
I evaluate the
integral (from x=0 to x=2) of the ingral (y=1 to y=+sqrd.root.of(4-x^2)of dydx
and come up with pi-2 = 1.14 but book answer is 1.23
pls help!!

The integral is the area of of the circle. So the total area should be:
The indefinite integral is

So did you calculate
Your book must be wrong. The area of a circle with radius is . You can show this using integration as I did above.
