Answer:
circle: 6490.9 cm², quadrant: 1622.7 cm²
Step-by-step explanation:
The circumference of the entire circle is known as 2πr and it is 4 times the given value, since a circle has 4 quadrants:
2πr = 4·71.4 = 285.6, so r = 285.6 / 2π ≈ 45.45
The area of a circle is πr², filling in the value for r we just found:
πr² = π 45.45² ≈ 6490.9 cm²
So the area of a quadrant is one fourth of that:
6490.9/4 = 1622.7 cm²
The question about "its area" can denote the entire circle, or just the quadrant, so two answers are provided.
Half the distance of AC (6)
The slope of a line with points (8, 42) and (3, 25) is -17/5
<h3>The first step in graphing data in a scatter plot</h3>
To graph a scatter plot, we simply determine the axis to plot each of the corresponding data
The axes are simply x and y axes
Hence, the first step in graphing data in a scatter plot is (d) Determine which axis corresponds to which data.
<h3>The slope of the line</h3>
The points are given as:
(8, 42) and (3, 25)
The slope of the line is calculated as:
m = (y2 - y1)/(x2 - x1)
This gives
m = (25 - 42)/(3 - 8)
Evaluate
m = -17/5
Hence, the slope of a line with points (8, 42) and (3, 25) is -17/5
