Determine the area of this shape. Express your answer in terms of pi.

mrs_skeptik [129]

The area of the composite shape is $21\pi\text{ sq. units}$

The shape is made up of four semi-circular regions. (see image attached to the solution). The area can be computed as follows:

$Area=(A-C)+(B-D)$

where each letter represents the areas of the associated semi-circles.

The area of a semi-circle is given by

$Area_s=\dfrac{\pi r^2}{2}$

For region $A$ , $r=6units$

$A=\dfrac{\pi\times6^2}{2}\\\\=18\pi \text{ sq.units}$

For region $B$ , $r=4units$

$B=\dfrac{\pi\times4^2}{2}\\\\=8\pi \text{ sq.units}$

For region $C$ , $r=3units$

$C=\dfrac{\pi\times3^2}{2}\\\\=4.5\pi \text{ sq.units}$

For region $D$ , $r=1units$

$D=\dfrac{\pi\times1^2}{2}\\\\=0.5\pi \text{ sq.units}$

So, the area of the shape is

$Area=(A-C)+(B-D)\\\\=[(18-4.5)+(8-0.5)]\pi\\\\=21\pi\text{ sq.units}$

-12 would fall into integers and real numbers.

-12 is not a natural number because it is negative.

-12 is not irrational because it can be transferred into a fraction, $- \frac{12}{1}$ .
