The Jacobian for this transformation is
with determinant 
, hence the area element becomes
Then the integral becomes
where 
is the unit circle,
so that
Now you could evaluate the integral as-is, but it's really much easier to do if we convert to polar coordinates.
Then
Answer:
6q or 6 * q
Step-by-step explanation:
As you do not know what the value of the variable q is, you are essentially changing it from word form to expression form.
"product" in math means multiply, so you are multiplying 6 with q.
6q is your answer.
