A parabolic goblet with a cup that is as wide as it is tall holds 1.74r^3 oz of water when it is full, where r is the radius in inches of the circular rim. What is the radius, to the nearest hundredth of an inch, of a goblet that holds 9 oz?
Cylinders
A cylinder is a three-dimensional solid shape with two parallel and congruent circular bases, joined by a curved surface at a fixed distance. A cylinder has an infinite curvilinear surface.
Cones
A cone is a three-dimensional solid shape having a flat base and a pointed edge at the top. The flat base of the cone tapers smoothly to form the pointed edge known as the apex. The flat base of the cone can either be circular or elliptical. A cone is drawn by joining the apex to all points on the base, using segments, lines, or half-lines, provided that the apex and the base both are in different planes.
