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:
[set r = 1.5 m]
⇒ 
⇒
m
One revolution of the water wheel corresponds to
meters so the angular velocity 15 rmp (revolutions per minute) corresponds to:
=
/min
Using this result, the speed of the river in kilometers per hour will be:
×
× 
⇒

⇒
≈
km/h
Answer:
36 3/4
Step-by-step explanation:
I understand now why it was wrong. I am so very sorry and I fixed the answer
Volume = L•W•H
3 1/2 • 7 • 1 1/2 = 36 3/4
.75 = 3/4
