Answer: 113.1

Step-by-step explanation:

Diameter = 12

We must find the radius. To do so, we divide the diameter by 2.

Radius = 6

Formula for finding the area of a circle: πr²

π = 3.14159265359

3.14159265359 × 6²

6 × 6 = 36

3.14159265359 × 36 = 113.097335529

Rounded to the nearest tenth = 113.1

Step-by-step explanation:

f°g= $f(g(x))$

$g(x)=x^2-6x$

$f(x)=1/x$

$f(g(x))=$ $\frac{1}{x^2-6x}$

if the denominator is zero the number is undefined which makes it not in the domain of the function

set $x^2-6x$ equal to 0

the values for x is 0 or 6

so the only value that is not in the domain of f°g is 0 and 6

Hope that helps :)
