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?

Answer 1

# Answer = 80cu.cm

# Explaination-

# Given-

For any coin,

r = d/2 = 2/2 = 1cm

l = 0.5cm

# Solution-

Plastic needed to make 1 coin=volume of coin

Plastic needed = πlr^2

Plastic needed = 3.14×0.5×1×1

Plastic needed = 1.57cm^3

For 50 coins,

Plastic needed = 50×1.57

Plastic needed = 78.5cm^3

Rounding it off to multiples of 10 we get 80 cu.cm.

We'll need 80ch.cm to make 50 coins...
