Answer:

\theta=1.72  radians

Step-by-step explanation:

Arc length and radius is given. So, we need to know the arc length formula for a circle.

That is:

s=r\theta

Where s is the arc length

r is the radius

\theta  is the angle (IN RADIANS)

We have:

s = 15.5

r = 9

Now, we substitute and find the angle:

s=r\theta\\15.5=9\theta\\\theta=\frac{15.5}{9}\\\theta=1.72

The angle, in radians, in 1.72

Answer:

1/2

((-2)^2-(4*2)^1/3)/abs(-2*2)

-2^2 = 4

4*2 = 8

-2*2 = -4 and abs of that is 4

4-(8)^1/3/4

8^1/3 = 2

4-2 = 2

2/4 = 1/2
