Monique wishes to make a lawn ornament in the form of a hollow sphere. The material being used to make the sphere weighs .075 pound per cubic inch. If the sphere's radius is 6 inches and thickness of the material of the finished ornament is 0.5. a. What is the volume of the lawn ornament? (Round to the two decimal places) b. What is the weight of the sphere, to the nearest pound?
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.
