A pulley with a radius of 36.2cm rotates at 6.5 rev/sec. Find the linear speed of the belt driving the pully. Round to the three significant digit.
------------------
The circumference of the pulley is 2(pi)r = 2(pi)36.2 = 72.4(pi) cm
------------------
At 6.5 rev/sec the belt moves at 6.5*(72.4(pi)) cm/sec
= 1478.433...cm/sec
