In cylindrical coordinates, the equations of the surfaces become
These surfaces intersect on the cylinder of radius 1 with cross sections parallel to the x,y-plane:
Then in cylindrical coordinates, the volume of the space bounded by these surfaces is
So multiple the largest eastern city by the smallest eastern city so 305 - 90
Then do the same for the western cities so 503 - 47
Now subtract the results to find the difference in the range of eastern vs western cities
Correct question:
Jada walks up to a tank that can hold up to 10 gallons. When it is active, a drain empties water from the tank at a constant rate. When Jada first sees the tank, it contains 7 gallons of water. Three minutes later, the tank contains 5 gallons of water. At what rate is the amount of water in the tank changing? use a signed number, and include the unit of measurement in your answer.
Answer: - 2/3
Step-by-step explanation:
Given the following :
Amount of gallon tank can hold = 10
tank drains at a constant rate :
First look tank contains 7 gallons
After 3 minute,
Tank contains 5 gallons
Thus signifies a 2 gallon decrease in volume of water after 3 minutes
Therefore, the rate of change =( change in volume) / time
Rate of change = (final volume - initial volume ) / 3
(5 - 7)/ 3 = - 2/3
IF they want to know the area you multiply all of them
So
16 x 20 x 8
You will get 2560
Multiply 325 and 5. Then divide 1500 and that answer! I will let you do the work
