Sector area = (Central Angle (Degrees) / 360) * PI * radius^2
One way to solve this is that an angle of (PI/4) = 45 degrees.
45 degrees is one eighth of a circle.
Area of ENTIRE circle = PI*radius^2 = PI * 3^2 =

Answer:
(-infinity, -7/3) U (10, infinity)
Step-by-step explanation:
Answer:
The value of p is -9.
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(p-3)/(9-6)
m=(p-3)/3
-4=(p-3)/3
-4*3=p-3
-12=p-3
p=-12+3
p=-9
