Answer:
hi there!
The correct answer to this question is 7.51
Step-by-step explanation:
you would use tangent for this question
tan(43) * 7 equals x
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:
x = 29
Step-by-step explanation:
(x + 3) + (x - 1) + (x + 1) = 90
3x + 3 = 90
3x = 87
x = 29
Answer:
I think that its x^2 + y^2 = 0.
I could be wrong...
