The arc length of the circle exists 846.65922 cm.
<h3>How to estimate the central angle in degree? </h3>
A unit circle by definition contains a radius of 1 unit.
We have to estimate the length of the arc subtended by an angle of radians.
arc length = radius angle
s = r
Where s be the arc length
r be the radius of the circle
be the angle measured in radians
arc length = 77cm
arc length = 77 7(3.14) / 2
arc length = 846.65922 cm
Therefore, the arc length of the circle exists 846.65922 cm.
