The correct answer would be 72.7%
Answer:
60 degrees
Step-by-step explanation:
C = 2(pi)r
The radius is 12 cm. We can find the circumference of a circle with radius 12 cm.
C = 2(pi)r = 2(3.14)(12 cm) = 75.36 cm
The length of the arc of the sector is 12.56 cm.
We can find the fraction this length is of the full circumference.
(12.56 cm)/(75.36 cm) = 1/6
The length of the arc of this sector is 1/6 the length of the circumference of the entire circle.
That means the angle of the sector is 1/6 the angle of an entire circle.
An entire circle has a central angle of 360 degrees.
1/6 * 360 degrees = 60 degrees

Answer:
a=28/5 or 5.6
Step-by-step explanation:
2a/7=a-4
Multiple both sides of the equation by 7
2a=7a-28
Subtract 7a from both side
2a-7a=-28

-5a=-26
Divide -5 from both side
a= 5.6
