3. A package of 23 medicated cough drops costs $3.00. What is the unit cost (unit rate)? O $0.11 per cough drop O $1.30 per cough drop O $0.13 per cough drop O $13.00 per cough drop

arc length = radius * x ( in radians)

6 * pi = 18 * x

divide by 18 on each side

6 pi / 18 = x

pi/3 = x

the angle is pi / 3 radians

or   60 degrees

set the two equations for y equal to each other. solve for x. this will be the x-coordinate for the point of intersection. use this x-coordinate and plug it into either of the original equations for the lines and solve for y.
