A loop wire is in a magnetic field of 2T. What is the magnitude of the magnetic flux?

0.2 m radius
B = 2T
30 degrees
and n is pointing out of the page

Ok so BAcos(30)
B= 2T
A= 3.14 r^2 for a circle right? (3.14)(0.2)^2
cos(30)

2T(3.14)(0.2)^2(cos(30))= 0.0335
and the answer is .22Wb??

Yes, if you have the orientation correctly.
