Concept explainers

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.

An experimental self-driving car is observed as it moves back an forth on a straight stretch of road. The car's velocity ( measured in meters per second) is a function of time (measured in seconds). The velocity is shown in the graph below. Positive velocities mean the car is moving toward the east and negative velocities mean its motion is toward the west. Using the values given below for the labeled areas in the graph, determine how far east of its starting position the car was at the end of t = 10 seconds.
