The answer is D. 12
4, 3 and 2 are all factors of 12 (least common denominator)
4.25x + 7 = 53.75
Subtract 7 from both sides:
4.25x = 46.75
Divide both sides by 4.25:
X = 46.75 / 4.25
x = 11
First find a parameterization for the curve of intersection.
Given the equation of a cylinder, a natural choice for a parameterization would be one utilizing cylindrical coordinates. Here,

which suggests we could use

with
, and we get
from the equation of the plane,

Now use the arc length formula:



First you need to combine like terms
13x+8-15x=6+x+11
-2x+8=x+17
-x -8 -x -8
-3x=9
--- ----
-3 -3
x=-3
