the angular velocity of a coil (Very tricky according to examiners report)?

Question

A generator is made from 100 turn coil, 3cm by 4 cm placed in a magnetic field of strength 0.1T. The coil rotates at 50 rev/sec. At a position when the magnetic field is perpendicular to the coil, calculate:

i) the amount of magnetic flux that passes through each turn
ii) the angular velocity of the coil and
iii) the peak voltage generated by the coil as it rotates

Problem is that the examiner gave answer to "ii)" as 1971.92 rad/sec. Which according to me seems incorrect.
But in the examiners report, he clear said that "100pi rad/sec" is not the correct answer.

Answer 1

Since there are 2π radians in one rev, I don't see how it could be anything other than 100π rad/sec

Answer 2

♣ additional details! this was the answer of a VIP’s daughter; and examiner belongs to his party! Hence 100pi rad/s is wrong; and any other boolshyt of hers is correct!
