Please help and show steps using the equations below the question. Thanks!

A 15-turn circular loop of wire is placed into a magnetic field with initial magnitude 3.9 T. The magnetic field is perpendicular to the surface of the loop. Over a period of 0.35 seconds, the strength of the field is decreased to 1.3 T and as the field decreases a 3.5 V emf is induced in the loop. Calculate the diameter of the loop of wire. (Give your answer in meters but don't include the units.)
