2. Find the area and circumference of the circle to the right.<br>16.6 m<br>

adoni [48]

Answer:

AREA:

$A=216.42m^2$

CIRCUMFERENCE:

$C=52.15m$

Step-by-step explanation:

The formula that is used to calculate the area of a circle is:

$A=\pi r^2$

Where "r" is the radius of the circle.

The formula for calculate the circumference of a circle is:

$C=2\pi r$

Where "r" is the radius of the circle.

Then, you need to find the radius. This is:

$r=\frac{16.6m}{2}=8.3m$

Substituting the radius, you get that the area and the circumference are:

AREA:

$A=\pi (8.3m)^2=216.42m^2$

CIRCUMFERENCE:

$C=2\pi (8.3m)=52.15m$

Which logarithmic equation is equivalent to the exponential equation below?

aleksandr82 [10.1K]

Option B: $\ln 6=5 x$ is the correct answer.

Explanation:

The exponential equation is $e^{5 x}=6$

If $f(x)=g(x)$ , then $\ln (f(x))=\ln (g(x))$

Thus, the equation becomes

$\ln \left(e^{5 x}\right)=\ln (6)$

Applying log rule, $\log _{a}\left(x^{b}\right)=b \cdot \log _{a}(x)$ and thus the equation becomes

$5 x \ln (e)=\ln (6)$

Since, we know that, $\ln (e)=1$ , using this we get,

$5 x=\ln (6)$

Hence, the logarithmic equation which is equivalent to the exponential equation $e^{5 x}=6$ is $\ln 6=5 x$

Thus, Option B is the correct answer.
