Procedure - Area of the shaded segment
The area of the shaded segment ([tex]A[/tex]), in square centimeters, is obtained by subtracting the area of the triangle from the area of the circle quarter, that is:
Area of the shaded segment
[tex]A = \frac{\pi\cdot r^{2}}{4}-\frac{1}{2}\cdot \left(\frac{\sqrt{2}}{2}\cdot r \right)\cdot \left(\sqrt{2}\cdot r\right)[/tex]
[tex]A = \frac{\pi\cdot r^{2}}{4}-\frac{1}{2}\cdot r^{2}[/tex]
[tex]A = \left(\frac{\pi}{4}-\frac{1}{2} \right)\cdot r^{2}[/tex] (1)
If we know that [tex]r = 14\,cm[/tex], then the area of the shaded segment is:
[tex]A = \left(\frac{\pi}{4}-\frac{1}{2} \right)\cdot (14\,cm)^{2}[/tex]
[tex]A \approx 55.938\,cm^{2}[/tex]
Where [tex]r[/tex] is the radius of the circle segment, in centimeters.
The area of the shaded segment is approximately 55.938 square centimeters. [tex]\blacksquare[/tex]
The length of the arc AB ([tex]s[/tex]) is determined by definition of circular arc:
Length of the arc AB
[tex]s = \frac{\pi}{2} \cdot r[/tex] (2)
If we know that [tex]r = 14\,cm[/tex], then the length of the arc AB is:
[tex]s = \frac{\pi}{2} \cdot (14\,cm)[/tex]
[tex]s \approx 21.991\,cm[/tex]
The length of the arc AB is approximately 21.991 centimeters. [tex]\blacksquare[/tex]
The perimeter of the figure ([tex]p[/tex]), in centimeters, is the sum of the arc AB and the two legs of the right triangle, that is:
Perimeter of the figure
[tex]p = \frac{\pi}{2}\cdot r + 2\cdot r[/tex]
[tex]p = \left(\frac{\pi}{2} + 2 \right)\cdot r[/tex] (3)
If we know that [tex]r = 14\,cm[/tex], then the perimeter of the figure is:
[tex]p = \left(\frac{\pi}{2} + 2 \right)\cdot (14\,cm)[/tex]
[tex]p \approx 49.991\,cm[/tex]
The perimeter of the figure is approximately 49.991 centimeters. [tex]\blacksquare[/tex]
The area of the triangle ([tex]A[/tex]) was used in the first part of this question and we proceed to extract it below:
Area of triangle AOB
[tex]A = \frac{1}{2}\cdot r^{2}[/tex] (4)
If we know that [tex]r = 14\,cm[/tex], then the area of the triangle AOB is:
[tex]A = \frac{1}{2}\cdot (14\,cm)^{2}[/tex]
[tex]A = 98\,cm^{2}[/tex]
The area of triangle AOB is 98 square centimeters. [tex]\blacksquare[/tex]
The area of the circle segment ([tex]A[/tex]) was used in the first part of this question and we proceed to extract it below:
Area of circle segment
[tex]A = \frac{\pi\cdot r^{2}}{4}[/tex] (5)
If we know that [tex]r = 14\,cm[/tex], then the area of the circle segment is:
[tex]A = \frac{\pi\cdot (14\,cm)^{2}}{4}[/tex]
[tex]A \approx 153.938\,cm^{2}[/tex]
The area of the circle segment is approximately 153.938 square centimeters. [tex]\blacksquare[/tex]
