Step-by-step explanation:
the length <em>s</em><em> </em>of the arc AC is given as :
s = r. 0
where
r = 10 is radius
0 = 90°
= π/2 rad is angle
s = 10. π/2
= 5π
= 5.3.14
= 15.7 ~ 16
The answer is A because it is less than 1-2
7.025 is greater than 7 1/8
Answer:
The angle has a measure of radians.
Step-by-step explanation:
According to the statement, an angle centered at the center of the circle covers an arc of units, the arc is a portion of the circunference. We include a figure representing the circle below.
Where:
- Radius, measured in units.
- Arc, measured in units.
- Angle of the arc, measured in radians.
From Geometry, we can calculate the length of the arc by means of this equation:
(1)
If we know that and , then the angle of the arc is:
The angle has a measure of radians.
