Write a method that calculates the weight of a copper disk of a given radius, r cm, if the density is 5.0 grams / square cm. Note that the disks are of all the same thickness, and the density is for that thickness. *** USE 3.14159 for the value of pi.*** calcWeight(1.0) → 15.70795 calcWeight(2.0) → 62.8318 calcWeight(3.0) → 141.37154999999998 ...Save, Compile, Run (ctrl-enter) |
