Answer:
The circumference of the circle is
.
Step-by-step explanation:
A sector is the part of a circle enclosed by two radii of a circle and their intercepted arc. A pie-shaped part of a circle.
The area of a circle is given by 
The formula used to calculate the area of a sector of a circle is:

The circumference of a circle is the distance around the outside of the circle and its given by

We know the central angle
= 110º and the area of the sector 50 units squared.
First, we use the formula to calculate the area of a sector to find the radius.

The radius can't be negative. Therefore,

Next, we apply the formula for the circumference of a circle.

Answer: 3.75 + - 7
Step-by-step explanation:
1.5x - 3 + 1.5x - 3 + 0.75x - 1
1.5x + 1.5x + 0.75x - 3 + - 3 + - 1
3.75x + - 7
