Explanation / Answer

1)
Arc Length = Theta * (pi/180) * r

Radius r = 40/2pi

Arc Length = 45 * (pi/180) * 40/2pi = 5 feet Answer

2)

Arc Length = Theta * (pi/180) * r

=>6 = Theta * (pi/180) * 54/2pi

=>Theta = 6*180/27 = 40 Degrees Answer

3)

Arc Length = Theta * (pi/180) * r

=>168= 42 * (pi/180) * r

=>r = (168*180)/42pi

=>r = 720/pi

Circumference = 2pi * 720/pi = 1440 meters Answer

4)

Arc Length = Theta * (pi/180) * r

Radius r = 10/2pi

Arc Length = 72 * (pi/180) * 10/2pi = 2 feet Answer

As per chegg Q&A guidelines I have answered first four parts , if you want more please ask a seperate question.
