Question

diameter of a wheel is 0.70 m how many rotations will the wheel complete in traveling a distance of 2.2 km​

Answer 1

Answer:pls mark me brainliest

if there is any mistake pls forgive

Step-by-step explanation:

your answer is 10000.

70/1000 = 0.0007 km

2 (0.0007/2) (22/7) = 22/10000  

2.2 / (22/10000) = 1000 (ans)

....

Answer 2

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

Step-by-step explanation:

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
• 1 km = 1000 m
• 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:

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.
