Radius of larger circle = 32
Area of larger circle:
= π • r²
= 3.14 • 32²
= 3.14 • 1024
= 3,215.36
Answer : 3,215.36 in²
Mean of a data = Sum of all observations ÷ Total number of observations
Mean of this data will be :
Sum of all observarions = 17 + 13 + 18 + 20 + 17 + 15 + 12 = 112
Total number of observations = 7
Mean = 112 ÷ 7
Mean = 16
Therefore the mean of this data set <em>=</em><em> </em><em>1</em><em>6</em><em> </em>
