a truck with a 16-inch radius wheels is driven at 77 feet per second. find the measure of the angle through which a point on the outside of the wheel travels each second.

one revolution = 2pi*r = 32pi inches

77 feet = 77*12 = 924"

$$\\\frac{924}{32\pi}\approx 9.19 \;\;rev/sec\\\\\\

\frac{924}{32\pi}\times 2\pi=57.75\;\; radians/sec$$
