Parameterize this surface (call it ) by
with and . The limits on should be obvious. We find the upper limit for by solving for where the sphere and cone intersect:
Take the normal vector to to be
(orientation does not matter here)
Then the area of is
Answer:
BCA
Step-by-step explanation:
All angles go to angles that have one curve to the angle that has the most curves, but I'm really guessing.
lines which do not intersect are always parallel and the answer will be parallel lines only...
6.113 i believe to be so
