It the measure of central angle ABC is π/2 radians ( 90° ) then the shaded sector represents 1/4 of the area of the circle.
Area of the circle:
A = r² π = 6² π = 36 π
A ( ABC ) = 36π : 4 = 6 π
Answer:
6 π units².

Answer:
B
Step-by-step explanation:
since the strongest correlation is either 1 or negative 1, and weakest is closer to 0,
now, lets order from weakest to strongest:
-0.52,0.65, 0.8, -0.87
Since -0.87 is closest to negative one than others to -1 or 1, it has the strongest linear relationship
Answer:
30°
Step-by-step explanation:
As the chord has same length of radius, the chord and the two radius form a equilateral triangle. Each angle of triangle is 60.So the chord subtended at the center is 60. So the angle subtended at the remaining part of the circle = 30°
The measure of angle between the tangent and chord = 30 {Alternate segment theorem}
