can someone pls help me i’m stressed out over this. all you have to do is find the area of the shaded part, thank you sm <3
Serggg [28]

Answer:

88.86

Step-by-step explanation:

Okay, first find the area of the circle (πr^2)

The diameter of the circle is 14, however we need the radius. Simply divide the diameter by two.

\pi 7^{2}

3.14*49 =153.86

Next, we find the area of the rectangle (bh)

13*5 =65

Subtract the rectangle from the circle.

153.86-65 =88.86

Hope this helps you :)

Which of the following sets of inequalities​
Ludmilka [50]

Inequalities help us to compare two unequal expressions. The correct options are 2 and 3.

<h3>What are inequalities?</h3>

Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.

The inequality for the red portion is,

slope, m = (-2/-4) = 1/2

y-intercept is 2.

y ≤ (1/2)x + 2

The inequality for the blue portion is,
slope, m = (5-0)/(3-0.5) = 2

y-intercept is -1.

y > 2x - 1

Hence, the correct options are 2 and 3.
