DVD stack shown below consists of 100 disks. The diameter of the each disk is 120 milimeters, the diameter of the hollow center of the disk is 15 millimeters, and the thickness is 1.2 milimeters. What is the volume of the stack in terms of π? 1,335,962π mm3 1,357,168π mm3 432,000π mm3
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.
