Question

3. A bicycle has wheels with a diameter of 622 mm. The

bicycle rolls forward and the wheel turns 5 radians.

How many millimeters forward did the bicycle move?

Distance = ( ) (622) = (15.708) ()

= (2.618)

Answer 1

1553.6mm

Explanation:

Given data

Diameter = 622mm

Radius= 622/2= 311mm

Circumference= 2πr

Circumference= 2*3.142*311

Circumference= 1954.32

Each revolution the wheels will turn 1954.32mm

Now let us convert radian to turns

1 radian= 0.159155 turns

5 radians= x turns

cross multiply

x= 5*0.159155

x=0.795 turns

If 1 turn will give 1954.32mm

0.795 turn will give x

cross multiply

x= 0.795*1954.32

x=1553.6mm
