Answer:
=452.16 ft^3
Step-by-step explanation:
Volume of cylinder formula: V=πr^2(h)
Note: Diamater/2=radius
Plug-in: V=3.14(4)^2(9)
=452.16 ft^3

all u had to do was plug it into y = mx+b
Answer:
The indifference point is 100 minutes.
Step-by-step explanation:
Giving the following information:
Plan a cost $23 plus an additional $.08 for each minute of calls.
Plan B cost $19 an additional $.12 for each minute of calls.
<u>First, we need to establish the total cost formula for each plan:</u>
Plan A= 23 + 0.08*x
Plan B= 19 + 0.12*x
x= number of minutes
<u>Now, to calculate the indifference point, we equal both formulas and isolate x:</u>
23 + 0.08x = 19 + 0.12x
4 = 0.04x
100= x
The indifference point is 100 minutes.
<u>Prove:</u>
Plan A= 23 + 0.08*100= $31
Plan B= 19 + 0.12*100= $31
A the first answer because the triangles are the same they are just flipped
