Answer:

  • B
  • C

_______________________________

A is wrong because radians really refers to the arc with respect to the angle. The opposite is true with A.

D is wrong because the arc is actually bigger than the radius given 1.5 radians.

E is wrong because the area of the whole circle is defined as 2π radians, 1.5 rad × 1.5 = 2.25 rad is (405/π)° and 2π radians is 360° (2π × 180 / π)°.

F is wrong because the circumference of a circle is 2πr.
