Rupert is copying some files from his computer to a compact disc, like the one shown above.

My name is Ann [436]

Option B: $11,304 \mathrm{mm} ^2$ is the area of the compact disc.

Explanation:

The diameter of the compact disc is $120mm$ .

To determine the area of the compact disc, let us substitute the values in the area of the circle formula,

$A=\pi r^2$ where $r=\frac{d}{2}$

Substituting the value of d in $r=\frac{d}{2}$ , we get,

$r=\frac{120}{2} =60$

Thus, $r=60$ and $\pi=3.14$ . Let us substitute these values in $A=\pi r^2$ , we get,

$A=3.14\times(60)^2$

Simplifying, we have,

$A=3.14\times3600$

Multiplying, we get,

$A=11304mm^2$

Thus, the area of the compact disc is $11,304 \mathrm{mm} ^2$

Hence, Option B is the correct answer.

Answer:

1. x > 4

2. m < 2

3. x > 2

4. x < -6

Step-by-step explanation:

These 4 inequalities will be solved the same way we solve equations. We take variables to one side and numbers to another and use algebra to solve. Each of them are solved shown below:

$4+6x$
