The solution to the problem is as follows:

Since given are :

s = length of arc = 35

r = 15

Use the formula:

s = r*theta

theta = s / r = 35 in / 15 in = 2.3 radians

Therefore, the angle of rotation of the blade is 2.3 radians.

I hope my answer has come to your help. God bless and have a nice day ahead!
