(a)
To determine : The
The conic section formed is ellipse.
Given information :
To use a new tube of caulk for the first time, its cone shaped tip is cut diagonally.
Explanation :
When a cone is intersected by a plane at an angle with respect to its base, the conic section formed is an ellipse.
Here, the cone shaped tip of a new tube of caulk is cut diagonally, so it will look like an oval.
Therefore, conic section so formed is an ellipse.
(b)
To determine : The conic section formed in the given situation.
The conic section formed is hyperbola.
Given information :
A pencil is sharpen with flat sides and each side intersects the cone shaped tip of the tube of caulk.
Explanation :
When a plane surface intersects a double cone at any point other than the center then a hyperbola is formed.
Here, a pencil is sharpen with flat sides and each side intersects the cone shaped tip of the tube of caulk.
Therefore, conic section so formed is a hyperbola.
