The class is about Electricity and Magnetism. The website wants exactly the perfect answer and in the same metric system units that are stated on the calculators that are on the picture for the question, if not, it'll mark it wrong.

Set 16 Problem 2 Dipole Moment of a Spinning Charged Ring A nonconducting circular ring, of inner radius R1 = 4.4 cm and outer radius R2 = 8.4 cm, carries a uniformly distributed charge @ = 0.032 uC. The ring rotates about an axis through its center at a rate of 1 revolutions per second. Determine its magnetic dipole moment u. 5 7 JC U = A.m2 abc sin(x) Ox10" Submit Reset Reset All .The magnetic dipole moment of the ring can be found by breaking it up into infinitesimal rings of thickness dr and radius r. Each infinitesimal ring has a dipole moment given by its current d/ times its area. Add up (integrate) the dipole moments du of the infinitesimal rings to find the total dipole moment . See Section 27-5 for a discussion of magnetic dipole moment. .To find the current d/ of an infinitesimal ring, divide the charge do on the ring by the period of the ring's rotation
