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.

15% off
15% off of 50
notice that 50 is 1/2 of hundred
15% of 100 is 15
therefor
15% of 50 is 15/2=7.5
that is discount
50-7.5=42.5
new price=$42.5
Subtract the minimum data value from the maximum data value to find the data range,so in this case yur data range is
10 - 0.08 = 9.92
so yur answer is 9.92
