kylie used wire fencing to form a border around a circular region in her back yard. if the
diameter of the circular region was 5 yards, what was the total length of the border,
rounded to the nearest tenth of a yard?
a.
15.7
b. 31.4
c. 78.5
d. 157.1

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
