Answer:
<h2>A= πr^2/4</h2>
Step-by-step explanation:
Step one:
given data
diameter of circle= 12 in
the radius is r=d/2=6in
the area of the circle is
A=πr^2
A=3.142*6^2
A=3.142*36
A=113.1in^2
If the circle is folded in half, the area will be A/2= 113.1/2= 56.55in^2
In the corresponding shape is folded again the area is A/4= 28.3in^2
<u>The expression for the last shape is </u>
<u>A= πr^2/4</u>
To find this out, subtract the tip from the total:
$128 - $86= $42
Then divide the 42 by 6:
42 / 6 = 7
So the waiter earns $7 per hour.

Answer:
5 in
Step-by-step explanation:
by doing a proportion of 2/4 for the known sides, you can find that the smaller triangle has sides that are half of the larger one. so 10/2 equals 5
