Question

Help please!


The radius of a cone-shaped tank is 4 feet less than its height. If the height of the tank is (x - 3) feet, the expression below shows the volume of the tank.

1/3 pi (x-7)^2 (x-3)

What does the factor pi ( x- 7)^2 (x-3) represent?
The area of the base of the tank

The area of the curved sides of the tank

The volume of 3 of the same cone-shaped tanks

The volume of 6 of the same cone-shaped tanks

Answer 5

It turns out that

Volume of Cone = (1/3)*(Volume of Cylinder)

where both the cone and cylinder have the same radius and height

Answer 6

So if you know the volume of a cylinder, you can find the volume of the cone with the same radius and height (just divide by 3 or multiply by 1/3)

Answer 7

is it C, right?

Answer 8

yep, you can take the contents of 3 cones and pour them all into the cylinder with the same radius and height as the original cone

Answer 9

and those two volumes will be the same

Answer 18

Which statement best defines the two quantities that are measured to find the rate at which an airplane descends?
The quantity of time measured in minutes depends on the quantity of speed measured in feet.
The quantity of speed measured in feet depends on the quantity of time measured in minutes.
The quantity of distance measured in feet depends on the quantity of time measured in minutes.
The quantity of time measured in minutes depends on the quantity of distance measured in feet.

Answer 19

thanks

Answer 20

were you able to get anywhere?

Answer 21

I am confused between b and c

Answer 22

hint:

speed = distance/time

Answer 23

speed is another way of saying "rate"

Answer 24

you're saying it's b ?

Answer 25

actually it's c because rate = distance/time

Answer 26

rate is defined how distance changes over time

Answer 27

okay I was 90 percent with c but was not sure :) thanks a lot !!!!

Answer 28

I have just one more that I am gonna post now

Answer 29

ok
