If you sub in z=1 and z=2 into the sphere equation you get:
So, you get:
i need to determine the surface area of the portion of the sphere that lies between the planes and
i have taken the derivatives with respect to x and y and have switched to polar coordinates and now i have the integral:
I am not sure what the limits of the integrals will be. But i am pretty sure the leftmost integral has the limits 0 to . can someone help me figure out the limits of the integrals? thanks.
