Answer:
The measure of the central angle whose radii define the arc is
Step-by-step explanation:
Radius of circle = 10 cm
Length of arc =
We need to find Theta
The formula used will be:
S= length of arc, r = radius and = angle
Putting values and finding \theta
So, the measure of the central angle whose radii define the arc is
<span>To find the mean absolute deviation of the data, start by finding the mean of the data set.
Find the sum of the data values, and divide the sum by the number of data values.
Find the absolute value of the difference between each data value and the mean: |data value – mean|.
Find the sum of the absolute values of the differences.
