Answer:


m(RS)=17 inches (answer rounded to nearest tenths)

Explanation:

Central angle there is 150 degrees.

The radius is 6.48 inches.

The formula for finding the arc length, RS, is


m(RS)=\theta \cdot r

where
r is the radius and
\theta ( in radians ) is the central angle.

I had to convert 150 degrees to radians which is
(150\pi)/(180) since
\pi \text{rad}=180^o.


m(RS)=(150\pi)/(180) \cdot 6.48


m(RS)=16.96 inches

Answer:
17\ in

Explanation:

You need to use the following formula for calculate the Arc Lenght:


Arc\ Length=2(3.14)(r)((C)/(360))

Where "r" is the radius and "C" is the central angle of the arc in degrees.

You can identify in the figure that:


r=6.48\ in\\C=150\°

Then, you can substitute values into the formula:


Arc\ Length=Arc\ RS=2(3.14)(6.48\ in)((150\°)/(360))\\\\Arc\ RS=16.95\ in

Rounded to the nearest tenth, you get:


Arc\ RS=17\ in
