Question

If a car wheel has a 14 inch radius through what angle does the wheel turn when the car rolls forward 5ft?

Answer 1

Angle will be 4.285 radian in degree it will be equal to
`245.677^(\circ)`

Explanation:

We have given radius of the car wheel r = 14 inch

And car rolls forward by 5 feet

So arc = 5 feet

We know that 1 feet = 12 inches

So 5 feet = 5×12 = 60 inches

Arc is equal to
`arc=radius * angle`

So
`60=14* \Theta`

`\Theta =4.285radian`

`=4.285* (180)/(\pi )=245.677^(\circ)`
