Answer:
Option C. 1.047 radians
Explanation:
We have to find the measure of angle AOT in radians.
To convert measure of an angle from degree to radians we use the formula

=
(Since measure of angle AOT is 60°)
=
(since π = 3.14)
= 1.047 radians
Therefore, option C. 1.047 radians is the correct option.
