A circle is characterized by radius, arc, sectors and circumference
- The length of the major arc is

- The radius of the circle is 15
- The area of the shaded sector is

<h3>Length of the major arc</h3>
The given parameters are:
--- the circumference
-- the center angle
The length of the major arc is calculated using:

So, we have:

Evaluate

Hence, the length of the major arc is 
<h3>The radius of the circle</h3>
The circumference is given as:

So, we have:

Divide through by 2pi

Hence, the radius of the circle is 15
<h3>The area of the shaded sector</h3>
The area of a sector is:

So, we have:

Evaluate

Hence, the area of the shaded sector is
