2.5 what just use the formula pi•(4/3r•r)
Answer:
1320 times
Step-by-step explanation:
Time = 1 h × (60 min/1 h) = 60 min
Revolutions = 60 min × (22 rev/1 min) = 1320 rev
The blades revolve 1320 times per hour.

Let's start by understanding that the graph is a linear line. We have a common difference if 4.5 for every 10x we have more.
We can start by finding the gradient, using rise over run. Let's take (10, 4.5) and (20, 9)
Our rise is 9 - 4.5 = 4.5 and our run is 10. Then, our gradient becomes 4.5/10 = 0.45
Now, we can substitute points using the point-slope form.
y - 4.5 = 0.45(x - 10)
y - 4.5 = 0.45x - 4.5
Hence, our line becomes y = 0.45x and you can verify by substituting in points from the table.
