For this case we use the following formula
Area of Sector = Area * radians of sector / 2 * pi radians
Where,
Area: it is the area of the complete circle.
We have then:
Area = pi * r ^ 2
Area = pi * (6) ^ 2
Area = 36pi
Substituting values:
5pi = 36pi * radians of sector / 2 * pi
Clearing:
radians of sector = ((5pi) * (2pi)) / (36pi)
radians of sector = (10pi ^ 2) / (36pi)
radians of sector = (10pi) / (36)
radians of sector = (10/36) pi
radians of sector = (5/18) pi
in degrees:
(5/18) pi * (180 / pi) = 50 degrees
Answer:
The measure of the central angle is:
50 degrees
Step-by-step explanation:
You can multiply everything by 7 to make things simpler.
3x + 5 = 4
3x = -1
x = -1/3
Answer:
10 hours
Step-by-step explanation:
45 pages=1.5 hours
300=x
x=300*1.5/45
x=10
What is it referring too? is there a graph to it???
