A wheel has a radius of 3.5 m. How far (path length) does a point on the circumference travel if the wheel is rotated through an angle of 71.0°? B) A wheel has a radius of 3.5 m. How far (path length) does a point on the circumference travel if the wheel is rotated through an angle of 71.0 rad? A wheel has a radius of 3.5 m. How far (path length) does a point on the circumference travel if the wheel is rotated through an angle of 71.0 revolutions?

Answer 1

pathlength=radius*angleinRadians.

Answer 2

a)2π . 3.5 . 71/ 360 = 4.33m

b) 2π . 3.5 . 71/ 2π = 248.5m

c) 2π . 3.5 . 71= 1561.37m
