An arc of length 30 meters is formed by a central angle a on a circle of radius 15. the measure of a in degrees (to two decimal places) 114.59 - right?

The median of a data set is the measure of center that is found by adding the data values and dividing the total by the number of data values that is the value that occurs with the greatest frequency that is the value midway between the maximum and minimum values in the original data set that is the middle value when the original data values are arranged in order of increasing (or decreasing) magnitude
