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 1 over 3(x - 7) represent?

The total surface area of the tank

One third of the radius of the tank

One third of the height of the tank

The total area of the base of the tank

check if below line has typoes :-

```
What does the factor 1 over 3(x - 7) represent?
```

lena772 · Answer

$$\frac{ 1 }{ 3 }(x-7)$$

directrix · Answer

For the volume, I got (1/3) *π * (x - 7)^ 2 * (x - 3)

anonymous · Answer

ohk... looking at the options, now  it makes more sense

anonymous · Answer

(x-7) is ur radius right ?

anonymous · Answer

i should have asked, 
if  $(x-3)$ is the height of tank, then $(x-7)$ is what ?

anonymous · Answer

height = x-3

radius = h-4
           = x-3-4
          = x - 7

anonymous · Answer

that means, (x-7) is the radius of tank 
so $\frac{1}{3}(x-7)$ is One third the radius of tank
