Question

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
(IT = 3.14).​

Answer 1

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
