By looking at the graph, we can see that the shape is a quarter of a circle.
The area of a circle is:
So, this "quarter circle" is:
R is the radius (the diagram shows the radius is 8), so we can now find the area:
The area is 8π.
Answer:
∠ RQS = 138°
Step-by-step explanation:
Since PR and PS are tangents to the circle, then
∠ QRP = ∠ QSP = 90°
The sum of the interior angles of PRQS = 360°
Subtract the sum of the interior angles from 360° for ∠ RQS
∠ RQS = 360° - (90 + 90 + 42)° = 360° - 222° = 138°
