The correct answer is 
<span>2) Calculate the area of the circle. Then, determine the central angle of the sector and divide this angle by 360° to get a fraction. Multiply ​the area of the circle​ by this fraction.
area of the circle is calculated by;
area = </span>πr² , where r- radius of circle
<span>the central angle of a circle is 360</span>°. Area of the circle is calculated for central angle of 360°. 
<span>Sector is when 2 arms/ radii enclose a central angle between them.
area for 360</span>° = πr²
<span>area for 1 </span>°    = area/ 360
<span>area for central angle of sector = area * angle/ 360
the angle of sector is divided by 360 and taken as a fraction .this fraction of the total area of the circle is taken as the area of the sector.

Which of the given values are in the interval (-3,1]?
Vladimir [108]

The values coming in the interval (-3,1] are -2, -1, 0, and 1.

<h3>What is defined as the term interval notations?</h3>
  • An interval is represented on a number line using interval notation. In all other sayings, it is a method of writing real number line subsets.
  • An interval is made up of numbers that fall between two specific data set.
  • Intervals can be categorized according to the numbers in the set.
  1. Interval Open: The endpoints of a inequality are not included in this type of interval.
  2. Interval Closure; The endpoints of a inequality are included in this type of interval.
  3. Interval with Half-Open Doors: This interval contains only one of inequality's endpoints.

The given interval notation is;

(-3,1], it is the case of half open half close.

-3 comes with the open interval, it means its value will not be included in the interval.

1 is with the closed interval, it means its value will be included in the interval.

Thus, the values lying between the interval (-3, 1] are  -2, -1, 0, and 1.

PLEASE HELP!!!<br> Find MG.<br> ∆EGF~∆EML.
stiv31 [10]

Answer:

MG=56\ units

Step-by-step explanation:

step 1

Find the value of x

we know that

If two triangles are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

In this problem we have that

∆EGF~∆EML

so

\frac{EG}{EM}=\frac{EF}{EL}

substitute the given values

\frac{5x+2}{16}=\frac{126}{28}

solve for x

5x+2=\frac{126}{28}(16)

5x+2=72\\5x=70\\x=14

EG=5x+2=5(14)+2=72\ units

step 2

Find MG

we know that

MG=EG-EM

substitute

MG=72-16=56\ units
