Answer:
Formula for the Arc length is given by:
As per the statement:
radius of circle(r) = 6 units
Angle () =
radian
Use conversion:
=
then;
substitute these given values we have;
Use value of
or
Simplify:
Therefore, the arc length of the arc substended in a circle with radius 6 units an angle of 7 pi/8 is 16.485 units
We will write it as a fraction in ordet to solve, that is:
We then operate as follows:
We have this, since 1 integer will be equal as a numerator divided by a denominator with equal values. Examples 1 = 2/2, 1 = 45/45, ...
