1. The problem statement, all variables and given/known data Use spherical cords to compute area of a disk, that's center at x,y=0, and z=4, having a radius of 3 2. Relevant equations I set up a triple ∫∫∫ (r^2* sin(theta)), running from phi =0 to 2pi, theta=0 to arcsin(3/5), r=5sin(theta) to 5. 3. The attempt at a solution It doesn't give me a current answer. What's wrong Am I even on the right track?
