ight circular cone is inscribed in a sphere. The base of the cone lies in the bottom half of the sphere. A dashed line segment goes from the vertex of the cone to a point in the center of the sphere. It is labeled 18 inches. The radius of the sphere has a length of 18 in. If the slant height of the cone has a length equal to that of its diameter, find the length (in inches) of the following. (a) the radius of the base of the cone (b) the altitude of the cone

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.
