We calculate as the linear velocity of the belt driving the pulley as follows:

angular velocity is related to linear velocity by the equation
 
v = wr

where v is the linear velocity, w is the angular velocity, and r is the radius.

v = 6 x 2π x 10
v = 376.99 m/s 

Therefore, the correct answer is option A.
