cylindrical cordinace?? 1. The problem statement, all variables and given/known data this is a two part question and is multiple choice part 1 Determine the type of the solid described by the given inequalities. 0 ≤ r ≤ 4, - pi≤ θ ≤ pi, -sqrt(16 − r^2) ≤ z ≤ sprt(16 − r^2) a half-cylinder a cylinder a half-sphere a sphere a parallelepiped part 2 Determine the type of the solid described by the given inequalities. 0<= theta <= pi/2 r <= z <= 5 a quarter of a cone a half-cone a quarter of a paraboloid a half-paraboloid a parallelepiped graphing in cylindrical confuses me. any help on how to attach these would be great. by looking at the second on i would assume it would be one the quarter somethings just because it is giong from 0 to pi/2 but dont know if that is right and if so how to tell the diff between cone or paraboloid??
