Answer:
We have to rotate spinner 108 degree counterclockwise to label i to label f.
Step-by-step explanation:
From the figure it is noticed that number of parts of spinner is 10. All are equal parts.
Central angle of a circle is 360 degree.
Since central angle divided into 10 equal parts, therefore central angle of each part is
\(\frac{360}{10}=36\)
From the figure it is noticed that f is on the third place of i in counterclockwise direction.
If we want to map i to f, the angle of rotation counterclockwise is
\(3\times 36^{\circ}=108^{\circ}\)
Therefore have to rotate spinner 108 degree counterclockwise to label i to label f.
