How do I complete this question on arc length?

tresset_1 [31]

Answer:

v ≈ 8.5 km/h

Step-by-step explanation:

Since the diameter of the wheel is 3 m the radius will be r = 1.5 m.

Use the radius of the water wheel to find it's circumference C:

$C=2\pi r$ [set r = 1.5 m]

⇒ $C=2\pi (1.5)$

⇒ $C=3\pi$ m

One revolution of the water wheel corresponds to $3\pi$ meters so the angular velocity 15 rmp (revolutions per minute) corresponds to:

$15(3\pi )$ = $45\pi$ $m$ /min

Using this result, the speed of the river in kilometers per hour will be:

$v=\frac{45\pi m }{1 min}$ × $\frac{1 km}{1000 m}$ × $\frac{60 min}{1 h}$

⇒ $v=8.48230016469$ $km/h$

⇒ $v$ ≈ $8.5$ km/h
