If there are exactly 2.54 centimeters in 1 inch, how many inches are in 1 centimeter Round to two decimal places.

Work Shown:

2.54 cm = 1 inch

2.54/2.54 cm = 1/2.54 inch   divide both sides by 2.54

1 cm = 0.39370078740158 inches

1 cm = 0.39 inches

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
