Answer:
Given the expression: 
Let the value of the given expression in radians be 
then;

......[1]
We know the value of 
Substitute the given value in [1] we have;

Since, the value of
is 0, therefore, the value of
is in the form of:
; where n is the integer.
At n =0, 1 and 2, {Since, n is the integer}
Value of
and
therefore, the answer in radians either
or
The total cost will be $20.21 because if u do $0.44×16 it will be $7.26 then, you will add $7.26+$12.95 together and get $20.21.
