Answer:

False

Step-by-step explanation:

Here is a counter example:

● f(x) = x^2

● g(x) = 3x

● (f○g)(x) = (3x)^2 = 9x^2 (1)

● (g○f)(x) = 3(x^2) = 3x^2 (2)

We can see that (1) and (2) aren't equal to each others.

Answer:

$f) \: r2 \div r1 \: = 5 \div 1$

Step-by-step explanation:

$\frac{a1}{a2} = \frac{1}{25} = \frac{\pi \times (r1)^{2} }{\pi \times (r2)^{2}}$

${(\frac{r2}{r1})}^{2} = 25$

$\frac{r2}{r1} = 5$
