As a first step, convert to cylindrical coordinates. The equation

is a clue to set


then have

and

. Meanwhile, the plane equation tells you to use

So we parameterize the part of the plane within the cylinder with the vector-valued function

The surface integral giving the area of the surface is

where

denotes the surface in question, and the surface element

is

We have



So the area is
Answer:
The percent attendance for that semester was 30%.
Step-by-step explanation:
In this problem, out of 190 students, only 57 students had perfect attendance. When a question says something like this, then it means that you are going to use division. You are going to divide 57 by 190.
57 ÷ 190 = 0.3
Now, multiply 0.3 by 100 to get the percentage.
0.3 * 100 = 30
So, the percentage of the perfect attendance is 30%.
Answer:
I do not think this is proportional.
