PLEASE i will give medal and fan :)
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?

anonymous · Answer

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

So which part of the question do you not understand? Do you understand how they got $$\frac{ 1 }{ 3 }\pi(x-7)^{2}(x-3)$$

anonymous · Answer

Basically, the factors represent the volume formula of a cone which is$$(\frac{ 1 }{ 3 })\pi*r ^{2}*h$$

anonymous · Answer

yeah i dont even know how they got that ..

anonymous · Answer

wait so the height 3?

hwtrain has it right :)
they gave a volume and asked what it would represent without the (1 over 3) part
and so the difference between  (1/3)volume and  volume
is a multiple of 3

anonymous · Answer

so do i multiply 1/3 * 3 ?

more like which option has "3" in it? :P

Lol i thought about that ... thank you !
