noname [10]

Answer: $log_39=2$ is the logarithmic equation which is equivalent to $3^2=9$ .

Step-by-step explanation:

According to the laws of logarithms

$log_b\ x=n$ ,where b=base ,n,x all are positive

It can be written in exponential form such as

$x=b^n$

Now in the given question x=9 ,b=3 and n=2 such that it will equals to

$log_39=2$

Hence the logarithmic equation for $3^2=9$ is $log_39=2$ .

Find the area of the shaded sector.

Vladimir [108]

Given that,

Radius of the circle, r = 8.91 cm

Angle, $\theta=81^{\circ}$

To find,

The area of minor sector.

Solution,

The formula for the area of minor sector is given by the formula as follows :

$A=\dfrac{\theta}{360}\times \pi r^2\\\\A=\dfrac{81}{360}\times \pi \times (8.91)^2\\\\A=56.11\ \text{cm}^2$

So, the area of the shaded sector is $56.11\ \text{cm}^2$ .
