The formula for the surface area of a cylinder is pi×2rh+2pi(r^2)
In this problem, r is 4 in and h is 16 in
The rate of change of the height is
in/min.
<h3>What is a right circular cylinder?</h3>
A right circular cylinder is a cylinder that has a closed circular surface having two parallel bases on both the ends and whose elements are perpendicular to its base. It is also called a right cylinder.
Volume of the cylinder = 
Rate of change of height is
= ?
At any time t,
Volume, V = 
Since r does not change with time, then r is a constant, so,
V = 
V = 
Differentiate both sides with respect to time t,
-------------(i)
Since
is given as 4
cu.in. per min,


in/min.
Hence, The rate of change of the height is
in/min.

The expected population of each country in 2025 are 22261221, 1465382683, 116537821 and 60347662
<h3>The expected population in 2025</h3>
The expected population of each country is calculated as:
P(n) = a *(1 + r)^n
Where:
- a represents the initial population
- r represents the growth rate
- n represents the number of years since 2000
2025 is 25 years since 2000.
This means that:
n = 25
So, we have:
<u></u>
<u>Australia</u>
P(25)= 19169000 * (1 + 0.6%)^25
P(25)= 22261221
<u>China</u>
P(25)= 1261832000* (1 + 0.6%)^25
P(25)= 1465382683
<u>Mexico</u>
P(25)= 100350000 * (1 + 0.6%)^25
P(25)= 116537821
<u>Zaire</u>
P(25)= 51965000* (1 + 0.6%)^25
P(25)= 60347662
Hence, the expected population of each country in 2025 are 22261221, 1465382683, 116537821 and 60347662

Um... well let's see what we got here.
It appears the two are 32 feet down in a hole, since they slipped 37 feet down from 5 feet above the ground. They have traveled a total of <span>5706.735 feet. To get that answer I took their initial height and added how far below ground level they went.
TBH I think you asked this question to make in unanswerable</span>
Answer:
I think it is Physical map but i may be wrong
Step-by-step explanation:
Political maps show how people have divided up the earth's surface. These maps show state and national boundaries, capitals, and large cities. Political maps use different colors to show different countries.
