Answer:
-1. is -3/7
Step-by-step explanation:
6×-4/11*7 ÷ (4/3×6/11)
-24/11×7 ÷ (4/3×6/11)
-24/77 ÷ (4/3×6/11)
-24/77 ÷ (24/3×11)
-24/77 ÷ 24/33
-24/77 × 33/24
-1/77 × 33
-33/77
-3/7

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.
