A boy who had discovered that 20 mm marbles fitted snugly into the bottom of a cylindrical jar, dropped in a fourth on top of the three and poured water enough into the jar to just cover them. How much water did he use?
Find the volume and total area of the sphere which circumscribes a cylinder of revolution whose altitude and diameter are each 6 inches.
Find the weight of the heaviest circular cylinder can be cut from a 16-lb shot.
A cylinder is inscribed in a given sphere. Find the shape of the cylinder if its convex surface area is a maximum.
A right circular cylinder is a cylinder whose base is a circle and whose elements are perpendicular to its base.
Cylinder is a solid bounded by a closed cylindrical surface and two parallel planes.
Solids in which V = Ab × h
This is a group of solids in which the volume is equal to the product of the area of the base and the altitude. Two types of solids belong to this group namely, prisms and cylinders.
Inscribe a circular cylinder of maximum convex surface area in a given circular cone.
Cut the largest possible rectangle from a circular quadrant, as shown in Fig. 40.
A cylindrical glass jar has a plastic top. If the plastic is half as expensive as glass, per unit area, find the most economical proportion of the jar.
