What is the area of the sector that is NOT shaded?
Kazeer [188]
Hey there! And welcome to Brainly.

Remember that the area of a circle is π*radius^2
Remember that there are 360<span>° in a circle.

</span>The angle of the unshaded part would be 360° minus the shaded part of 60<span>°.
</span>360°- 60° = 300<span>°
</span>Since the area of a circle is πr^2, and the section of the circle is 300°, or 300/360 = 5/6 or one full circle, the area of the unshaded region is
(5/6)π*radius^2
= (5/6)π*12^2
= 120π units^2

Y greater than or equal to x + 4
tatiyna

See the attached files

<h2>Explanation:</h2>

Here we have the following inequality:

y>x+4

In order to graph the shaded region, we have to graph the equation of the line y=x+4 whose slope is m=1 and y-intercept b=4.  So the graph of the line is shown in the First Figure below.

To find the shaded region we need to have a look at the symbol > that indicates that the shaded region is above the graph of the line and. Since this doesn't include the symbol =, then the line is dotted. Therefore, the resulting region is shown in the second Figure.
