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!
