HELP!!!

A patient having an MRI scan forgot to remove their wedding band. The gold ring is 1.9cm in diameter. Gold's electrical resistivity is 2.2 milli-ohm. The magnetic Field in the MRI solenoid is directed along the person's body from head to foot, so the ring is oriented perpendicular to the MRI's magnetic field. As the scan is taken, the magnetic field from the solenoid through the ring increases from 0.2T to 1.6T with 0.8seconds. See the diagram provided. Find... a) The angle theta between the magnetic field and the plane of the ring. b) The area of the ring in meters squared. c) The change magnetic field through the ring over time in Tesla/second. d) The magnitude of the induced emf in Volts. e) The current induced by this emf in Amps
