Question

Will fan and award :)
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 over 3π (x - 7)2 (x - 3)

What does the factor π(x - 7)2 (x - 3) represent?

Answer 1

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 2

it might help if you rewrite the formula.
1/3π (x - 7)2 (x - 3)

where π (x - 7)2 (x - 3) = abc (just a placeholder name)

so you have volume = 1/3 * abc
what is abc?

Answer 3

Im stilll confused, is there any other way you could put it? would abc be the answer im looking for?

Answer 4

\[\frac{ 1 }{3 } * abc\]= volume of the tank.

what is abc? (hint it's 3 times the above quantity)

Answer 5

its 3 times 1/3 ?

Answer 6

How do you get \[\frac{1}{3}x -> x\]

Answer 7

aha i get it , thanks

Answer 8

lol should have used x instead of abc

Answer 9

yes , but either way , was still fine :)
