I nee help with this question

Find the value of tan theta if sin theta = 12/13 and theta is in quadrant 2

Consider the integral: 4 0 16 − y2 − 16 − y2 4 1 x2 + y2 dz dx dy . (a) describe w. use the standard view of the x, y, and z axes. front half of a cone with a rounded top. full cone with a flat top. right half of a cone with a flat top. front half of a cone with a flat top. right half of a cone with a rounded top.

Need this asap if anyone can i would be very grateful. if you could show workings that would really
