Answer:

530.66mm²

Step-by-step explanation:

Area of a circle = $\pi r^{2}$

r(radius) = 13mm

Area = (3.14 × 13²)mm²

= (3.14 × 13 × 13)mm²

= (3.14 × 169)mm²

= 530.66mm²

Hope this helps :))

Answer:

$-37\leq x\:$

Step-by-step explanation:

To find the values of $x$ for which, the value of $\frac{3-x}{8}$ belongs to $(-2,5]$ ,we solve the inequality;

$-2\:$

We multiply through by 8 to obtain;

$-16\:$

We subtract 3 to get
