Answer:
8pi feet per second
Or, 25.1 feet per second (3 sf)
Step-by-step explanation:
C = 2pi×r
dC/dr = 2pi
dC/dt = dC/dr × dr/dt
= 2pi × 4 = 8pi feet per second
dC/dt = 25.1327412287

Hey there!
You can plug this into the slope equation to find the slope.
m= (y2-y1)/(x2-x1)
Plug in two points. I chose (0,4) and (1,7).
m= (7-4)/(1-0)
m= (3)/(1)
m= 3
3 is your answer.
I hope this helps!
