What is the arc length of the arc sub tended in a circle with radius 6 and an angle of 7 pi/ 8

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

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
