Question

The diameter of the wheel is 0.6 m. How many rotations will the wheel complete while travelling of 1Km 980m?​

Answer 1

Answer:

The number of rotation a wheel complete to cover 1980 m is 1000.

Step-by-step explanation:

Given that:

The diameter of the wheel of a vehicle is 0.63 m.

→ Radius of wheel = 0.63/2 = 0.315 m

Converting distance 1 km 980 m into m:

1 km = 1000 m

1 km 980 m = (1000 + 980) m = 1980 m

To Find:

Number of rotation a wheel complete.

Formula used:

Number of rotation = (Total distance)/(Circumference of wheel)

Number of rotation = (Total distance)/(2πr)

Finding the number of rotation a wheel complete to cover 1980 m:

Number of rotation = (1980)/(2 × π × 0.315)

Number of rotation = (1980 × 7)/(22 × 0.63)

Number of rotation = 1000
