A concrete sidewalk is to be be built around the outside of the corner lot that measures 140ft by 180 ft. The side walk is to be 5ft wide. What is the surface area of the side walk? The side walk is to be 4 in. Thick. How many cubic yards of concrete are needed? How much will it cost at $90/yd^3?
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.
