Step-by-step explanation:

we will find the area of the inner circle and then the area of the outer circle and see what the ratio is between those 2

area of a circle = $\pi$ $r^{2}$ (where r is the radius, NOT the diameter, easy to confuse)

the radius of the inner circle is 2.5. which is half of the diameter of 5

inner circle = $\pi$ *(2.5)^2

inner circle = 19.6349...

outer circle = $\pi$ *(10^2)

outer circle = 314.1592...

the ratio is 19.6349... / 314.1592... = 0.0625

0.0625 = 6.25%

= 6% ( rounded to nearest whole number )

$ln\hspace{1mm} e^3=3$ , $ln\hspace{1mm} e^{2y}=2y$

Step-by-step explanation:

We know that $ln \hspace{1mm} e =log_e e= 1$ and according to power rule:

ln(x^y) = y ln(x)

Thus,

$ln\hspace{1mm}e^3=3 ln\hspace{1mm} e =3$

$ln\hspace{1mm}e^{2y}=2y ln\hspace{1mm} e = 2y$
