The inside of a vase is an inverted cone 2.983 in. across the top and 5.016 in. deep. If a heavy sphere 2.498 in. in diameter is dropped into it when the vase is full of water, how much water will overflow?
A sphere of radius a is dropped into a conical vessel full of water. Find the altitude of the smallest cone that will permit the sphere to be entirely submerged.
A sphere is cut in the shape of a circular cone. How much of the material can be saved?
Find the altitude of the circular cone of maximum convex surface inscribed a sphere of radius a.
This is a group of solids in which the volume is equal to one-third of the product of base area and altitude. There are two solids that belong to this group; the pyramid and the cone.
The lateral area of frustum of a right circular cone is given by the formula
R = radius of the lower base
r = radius of the upper base
L = length of lateral side
Find the largest right pyramid with a square base that can be inscribed in a sphere of radius a.
A sphere is cut to the shape of a circular cone. How much of the material can be saved? (See Problem 63).
Inscribe a circular cylinder of maximum convex surface area in a given circular cone.
For the silo of Problem 57, find the most economical proportions, if the floor is twice as expensive as the walls, per unit area, and the roof is three times as expensive as the walls, per unit area.
