**Find the volume of the portion of cone z^2 = x^2 + y^2 bounded by the planes z = 1 and z = 2 using spherical coordinates**

I am having trouble coming up with the limits

I am having trouble coming up with the limits

**Relevant equations**

dV = r^2*sin(theta)*dr*d(theta)*d(phi)

r = sqrt(x^2+y^2+z^2)

the problem is actually 2 parts, the 2nd part asks to evaluate by cylindrical coordinates and I obtain 7pi/3 which i know is right, I just can't come up with the limits

**Attempt**

for r i have from sqrt2 to 2sqrt2

for theta i have from 0 to pi/4

and for phi i have from 0 to 2pi
