A 12,0 -cm-diameter loop of wire is initially oriented perpendicular to a 1.5 T magnetic field. (a) Find the magnetic flux through the loop. (b) If the loop is rotated so that it's plane is parallel to the field direction in 0.20 s , what is the average induced emf in the loop?

diameter of coil= 12 cm
magnetic flux through the loop say `phi`
=`1.697xx10^(-2)/.20=8.486xx10^(-2) ` V
