Radius = 5 cm
circumference = 2*PI*radius
circumference = 31.4159 cm
The circumference is of the entire circle.
60 degrees is 1/6 of the circle so the subtended arc =

Answer:
number of standard-delivery package x = 60
number of express-delivery package y = 30
Step-by-step explanation:
We have:
Total number of packages shipped one day = 90
Total shipping chages for the day = 555 $
Charged for each standard-delivery package = 4.5 $
Charge for each express-delivery package = 9.5 $
Let call x number of standard-delivery package. and
y number of express-delivery package .
Then x + y = 90
And 4.5* x + 9.5* y = 555
we get a 2 equation system, solving
y = 90 - x
4.5*x + 9.5 * ( 90 - x ) = 555
4.5*x + 855 - 9.5*x = 555
- 5*x = -855 + 555
5*x = 300
x = 60
And then y = 90 - 60
y = 30
