Answer:

We have to rotate spinner 108 degree counterclockwise to label i to label f.

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

(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

$3* 36^(\circ)=108^(\circ)$

Therefore have to rotate spinner 108 degree counterclockwise to label i to label f.
