Every integer is a rational number, since each integer n can be written in the form n/1. For example 5 = 5/1 and thus 5 is a rational number. However, numbers like 1/2, 45454737/2424242, and -3/7 are also rational.

A = 201 cm²
Step-by-step explanation:
We know that the area of a circle can be calculated with the formula:

with d being the diameter.
Therefore:
A = 3.14(8cm)² = 201 cm²

We carry out the multiplication first.
-2 × 5 = -10
</span><span>-2×5+-8
= -10 + -8
+(-) = -
</span>
<span> -10 + -8 = -10 - 8 = - (10 + 8) = -18
I hope this helps.</span>
