The relationship of arcs is:
S '/ S = ((1/9) * pi * 3) / (2 * pi * 3)
Rewriting we have:
S '/ S = ((1/9)) / (2)
S '/ S = 1/18
Therefore, the area of the shaded region is:
A '= (S' / S) * A
Where A: area of the complete circle:
A '= (1/18) * pi * r ^ 2
A '= (1/18) * pi * (3) ^ 2
A '= (1/18) * pi * 9
A '= (1/2) * pi
Answer:
The area of the shaded region is:
A '= (1/2) * pi
Percent decrease is really interesting
Let us solve this quickly.
80-17=63
63/80 = 0.7875
Percent decrease is 78.75%
All linear functions are in the form
y = mx + b.
m = slope
b = y-intercept
If you know the slope, which means rise divided by run and the y-intercept which is a constant, you can graph any linear function. A linear function is a STRAIGHT LINE. The word linear means STRAIGHT LINE.
The square root of 9 is 3
