Please help me with this problem, I don't know how to do it. Please! Please! Thanks in advance.

An ac generator has a circular coil of 500 turns and diameter 0.640 m which rotates about an axis in the plane of the coil and through its center. The coil rotates at 97.5 revolutions per second in a uniform magnetic field 0.240 T which is perpendicular to the axis of rotation. Give your answers to at least three significant figures.

1. What is the peak emf (in V) generated across the generator coil?
2. What is the rms emf (in V) generated?
