Answer:
3/10
Step-by-step explanation:
10 is the denominator 3 is the numerator
I gather you're supposed to compute the integral of over a surface that is the part of the parabolic cylinder with and .
We can parameterize by
with the given constraints on and . Take the normal vector to to be
so that the surface element is
Then in the integral, we have
28.26
circumference= 2πr or πd (diameter)
9 x 3.14=28.26
