alleryWhy are these curves called conics?
AThey complete a cone
BThey compress a cone
CThey come from a cone
DThey cover a cone
Answer & Solution
Correct answer: C. They come from a cone
1. The name points to how the curves are produced.
2. Each arises from slicing one solid.
3. They are known as conic sections because they can be obtained as intersections of a plane with a cone.
4. So the answer is they come from a cone.
