PROBLEMS
7.1 A cone of base diameter 3-in and height 3.5-in is sectioned by a plane at an
angle of 45 with the axis of the cone at a height of 2-in. Draw development for the
truncated cone.
7.2 A cone of base diameter 6-in having an altitude of 5-in is penetrated on one side by a cylinder of 2.5-in diameter such that the axis of the cylinder bisects the axis of the cone
at right angles. Draw the curves of intersection in the top and the front views.
7.3 Draw development for a right pyramid having an altitude of 6-in with a square
base of size 5 x 5-in.
