Answer:

Value of $f^{-1}(\{4\})$ is 8.

Step-by-step explanation:

Given function,

$f(x)=\big[\frac{x}{2}\big]$

we have to find : $f^{-1}(\{4\})$

It is known that,

$[x]$ =the greatest integer <=x

Then,

$f(x)=\big[\frac{x}{2}\big]$

$\implies x=f^{-1}(\big[\frac{x}{2}\big])$

Taking x=8 we get,

$f^{-1}(\big[\frac{x}{2}\big])=x$

$\implies f^{-1}(\big[\frac{8}{2}\big])=8$

$\implies f^{-1}([4])=8$

$\implies f^{-1}(\{4\})=8$ ( Since [4]=4 )

Hence the value of $f^{-1}(\{4\})$ is 8.

Volume of a cylinder = πr² * l

V = 12²π * 20

V = 144π * 20

V = 2880π

The answer is therefore the third one down, 2880 π in³
