The center is (-2,-1) and another point on the circle is (6,5)

Hello,
Radius²=(6+2)²+(5+1)²=64+36=100=10²

Circle: (x+2)²+(y+1)²=100

The major difference is that a histogram is only used to plot the frequency of score occurrences in a continuous data set that has been divided into classes, called bins.  bar charts, on the other hand, can be used for a great deal of other types ofvariables  including  ordinal  andnominal  data sets.
