Question

∫∫RSin(y)dA
Where R[0,2]x[0,pi]

a) Sketch the solid region represented by this double integral

c)Use a geometric interpretation of the double integral and
symmetry in the solid region to determine an exact value for this
double integral. NOTE: No credit will be given for evaluating the
double integral using an iterated integral expression. @zepdrix

Answer 1

Answer 2

I checked the answer using iterated integral and the answer is 4

Answer 3

Have you tried sketching the solid region?

Answer 4

Assume it's a rectangle.
