C. The charge of each minute of a call is $0.40
Step-by-step explanation:
We look at the point (1, 0.4)

Answer:
1.5748
Step-by-step explanation:
The legnth is irrelivant
we know that
Circumference=2 times pi time radius
c=40
40=2 times pi times radius
divide both sides by 2
20=pi times radius
divide both sides b pi
20/pi=radius
the radius is 20/pi cm or aproximately 6.366199048 cm
If you multiply 2/3 by a product less then 1 you will get a product that is less then 2/3
