Sagot :
The arc length of the circle exists 846.65922 cm.
How to estimate the central angle in degree?
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 [tex]7\pi/2[/tex] radians.
arc length = radius [tex]*[/tex] angle
s = r[tex]$ * \theta[/tex]
Where s be the arc length
r be the radius of the circle
[tex]\theta[/tex] be the angle measured in radians
arc length = 77cm[tex]$*7\pi/2[/tex]
arc length = 77 [tex]*[/tex] 7(3.14) / 2
arc length = 846.65922 cm
Therefore, the arc length of the circle exists 846.65922 cm.
