Question

Your company makes game parts using 3-D printers. One customer wants a circular game coin that is 2.0 centimeters across and 0.5 centimeters thick, as shown below. You need to estimate the amount of plastic you will need for each batch of 50 coins. How many cubic centimeters is that, rounded up if necessary to be a multiple of 10 cubic centimeters?

The tip jar contains $42.60. You share equally with 2 other sandwich makers. What is your share?

Answer 1

Answer:It will be 80 cubic centimeters

Step-by-step explanation:The coin is in a shape of a cylinder and the formula for the shape of a cylinder is volume=radius^2 times height, you can enter your values of radius=1 because radius is half of the diameter and height=0.5. Thus your answer for 1 coin is 1.571 and you multiply that times 50 because you want to make 50 coins and you get 78.55 cubic centimeters. Then you need it to be a multiple of 10 so 78.55 is closer to 80 than 70.
