Question

the diameter of a wheel of a vehical is 0.70m long .How many rotation will it take complete in travelling a distance of 2.2km?​

Answer 1

Answer:

• The wheel will rotate 1000 times to complete the distance of 2.2 km.

Step-by-step explanation:

Given that:

• Diameter of a wheel of a vehicle = 0.70 m
• Total distance = 2.2 km

To Find:

• How many rotations will the wheel complete in travelling a distance of 2.2 km?

Finding the circumference of the wheel:

We know that.

Circumference of a circle = π × Diameter

Circumference = (22 × 0.70)/7

Circumference = 2.2

∴ The circumference of the wheel = 2.2 m

Converting the total distance in m:

We know that.

1 km = 1000 m

2.2 km = (2.2 × 1000) m

2.2 km = 2200 m

Finding the number of rotations taken by wheel to complete the distance:

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

Number of rotation = 2200/2.2

Number of rotation = 1000

∴ The number of rotations taken by wheel to complete the distance = 1000

Answer 2

$\small{\textsf{\textbf{\underline{\underline{The number of rotations taken by wheel to complete the distance = 1000 rotations \::}}}}}$

Step-by-step explanation:

Given that:

• Diameter of a wheel of a vehicle = 0.70 m
• Total distance = 2.2 km

To Find:

• How many rotations will the wheel complete in travelling a distance of 2.2 km.

formulas used:

• Circumference of a circle = π × Diameter
• Number of rotation = (Total distance)/(Circumference)

Finding the circumference of the wheel:

We know that.

Circumference of a circle = π × Diameter

Circumference = (22 × 0.70)/7

Circumference = 2.2

➠ The circumference of the wheel = 2.2 m

Converting the total distance in m:

• We know that.
• 1 km = 1000 m
• 2.2 km = (2.2 × 1000) m
• 2.2 km = 2200 m

Finding the number of rotations taken by wheel to complete the distance:

• Number of rotation = (Total distance)/(Circumference)
• Number of rotation = 2200/2.2
• Number of rotation = 1000
