The perimeter of a circle:
P=2πr=πd, where r ia radius and d is diameter.
Here, it is a semicircle, a half of a circle
12×2πr=πr is the perimeter
d=10r=102=5
P=(π×5)+10
=(3.142×5)
15.71+10=25.71cm

A circular loop of flexible iron wire has an initial circumference of 165.0 cm, but its circumference is decreasing at a
constant rate of 12.0 cm/s due to a tangential pull on the wire. The loop is in a constant, uniform magnetic field oriented
perpendicular to the plane of the loop and with magnitude 0.500 T.
(a) Find the emf induced in the loop at the instant when 90 s have passed.
(b) Find the direction of the induced current in the loop as viewed looking along the direction of the magnetic field.
