1.Which explanation justifies how the area of a sector of a circle is derived?

1 answer:

5 0

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.

A quilt is designed using a square pattern. each square contains two rectangles. each rectangle contains a shaded rhombus. each

Xelga [282]

Based on the calculations, the value of x in this rhombus is equal to: B. 55.

<h3>How to determine the value of x?</h3>

Since the opposite angles in a rhombus are always congruent, the sum of each angle in any rhombus must be equal to 360 degrees.

From the image of the rhombus, we can deduce the following parameters:

Adjacent angles = 2x + 20 and 50 degrees.

Opposite angles = 2x + 20 and 50 degrees.

Adding the angles, we have:

2x + 20 + 2x + 20 + 50 + 50 = 360

4x + 140 = 360

4x = 360 - 140

4x = 220

x = 220/4

x = 55°

Determine the 5th term of the sequence 1, 10, 100,

balu736 [363]

To determine the 5th term you need to find the 4th. This doesn’t work for all but for this one you just add a zero at the end. So the 4th term is 1,000 and that makes the 5th term 10,000

mr_godi [17]

Answer:

Step-by-step explanation:

When you go from x=1 to x=3 you go up twice on the x-value. The y value also increases by 6 which means all you have to do is find the average.

6/2= 3

3 is the average increase between x=1 and x=3

Hope this helps!
