The total volume of the three cylinders is given by:
V = (3) * (pi) * (r ^ 2) * (d)
Where,
r: cylinder radius
d: cylinder depth
Substituting values we have:
V = (3) * (3.14) * (4 ^ 2) * (7)
V = 1055.04 feet ^ 3
Answer:
the volume of oil needed is:
V = 1055.04 feet ^ 3
<h3>Answer: 395 birds</h3>
==============================================
Work Shown:
The formula to use is
A = P*(1+r)^x
where,
P = 12000 is the initial population
r = -0.15 represents the growth rate in decimal form; which is really a decay/decrease due to r being negative
x = 21 days have passed by (3 weeks = 3*7 = 21 days)
These values lead to...
A = P*(1+r)^x
A = 12000*(1+(-0.15))^21
A = 12000*(1-0.15)^21
A = 12000*(0.85)^21
A = 12000*0.03294560142183
A = 395.34721706196
A = 395

-1 times the second equation = 
= 
--4
Now we are given that replace the third equation by the sum of itself and -1 times the second equation
So, New third equation = 
=
Hence the new third equation is
