Answer:
9.42 ft
Step-by-step explanation:
Two gates are fitted at the entrance of a library. To open
the gates easily, a wheel is fixed at 6 feet distance from
the wall to which the gate is fixed. If one of the gates is
opened to 90°, find the distance moved by the wheel
Distnace moved = (90/360) * 2 π R
= (1/4) * 2 * 3.14 * 6
= 9.42
the distance moved by the wheel = 9.42 ft
