Find the magnitude of the average induced emf

A circular loop in the plane of the screen lies in a 0.84 T magnetic field pointing into the screen. If the loop's diameter changes from 19.0 cm to 6.0 cm in 0.50 s, determine the following.

(a) What is the magnitude of the average induced emf?

(b) If the coil resistance is 2.5 , what is the average induced current?
