How do I solve, A catering group that has a chef, a salad maker, and a server cost the customer $70 per. hour. The salad maker c
osts $5 per hour more than the server. The chef costs the same as the salad maker and the server cost together. Find the cost per hour of each member of the catering group.
c = circumference
pi = 3.14
r = radius = 9 inches
d = diameter
c=pi*d
The radius is half of the diameter, d = 2r. Then d = 2*9=18.
plug into equation. c= pi*d = 3.14*18
round accordingly and you may want to include that the measurement you end up with is in inches.
