Hello, I need help with the following two homework question for my class. Can you please help? Also, please place details on how to solve it. I need them for my notes.

1.

Find the volume between the cone .1: = x/y2 + 22 and the sphere centered at (0, 0, 0) of radius 2. Use Spherical coordinates. For the differentiable function h(x, y), we are told that h(600, 100) = 300 and hx (600, 100) = 12 and hy (600, 100) = -8; estimate h(604, 99)
