Answer:
330 degrees
Step-by-step explanation:
The arc length is equal to the circumference time the fractional part of the circle
arc length = circumference * x/360
11 = 12 * x/360
Divide each side by 12
11/12 = 12/12 *x/360
11/12 = x/360
Multiply by 360
11*360/12 = x /360 *360
330 = x
The central angle is 330 degrees
