Absolute Value – Area CHARTS & TABLES
Absolute Value
The absolute value of a number is the number itself, without a positive or negative
sign in front of it. For example, the absolute value of –3 is 3, and the absolute value
of +5 is 5. Instead of writing out the words, “the absolute value of” a quantity, the
symbol for absolute value | |is used to express the same idea, like this: |–3|.
To solve for the absolute value of a number, the answer is the number itself. In other
words, it is the number without the positive or negative sign. Here are some
examples:
|–3|= 3
|+3|= 3
| 3 |= 3
|+5|= 5
|–72|= 72
|–9|= 9
| 0 |= 0
If a number does not have asign in front of it, it is considered a positive number, as
in the example | 3 |above.
Zero is neither a negative nor a positive number, but the absolute value of 0 is still 0.Area
Area is the surface space of a figure.
Here is how to calculate area (A)for a variety of figures:
Circle
Area = π×the square of the radius
A=πr^2
Parallelogram
Area = base ×height
A=bh
Rectangle/Square
Area = length ×width
A=lw
