Question

diameter of a wheel of a cycle is 70 cm. it moves slowly along the road how far will it go in 24 complete revolutions

Answer 1

Answer:

Step-by-step explanation:

GIVEN:

Diameter of a wheel = 70 cm

No. of revolutions completed by a wheel = 24

TO FIND:

What is the distance covered by the wheel ?

SOLUTION:

We have given that the diameter of the wheel is 70 cm

❝ Hence, the Distance covered by the wheel is 5280 cm ❞

Answer 2

Given:-

• Diameter of a wheel = 70 cm
• No. of revolutions completed by a wheel = 24

To find:-

• Find the distance covered by the wheel ?

Solution:-

The diameter of the wheel is 70 cm.

=> diameter/2

=> 70/2

=> 35 cm.

• Radius = 35cm.

We know that,

The circumference of the wheel = 2πr

According to question:-

=> 2 × π × r

=> 2 × 22/7 × 35

=> 2 × 22 × 5

=> 220cm

The distance covered by the wheel.

=> No. of revelation = distance/circumference

=> 24 = distance/220

=> distance = 220 × 24

=> distance = 5280cm

Hence, the distance covered by the wheel is 5280 cm.

Some Important:-

Speed, Time and Distance:

• Speed = Distance/Time
• Time = Distance/speed
• Distance = Speed × Time

km/hr to m/sec conversion:

• x km/hr = x × 5/18 m/sec.

m/sec to km/hr conversion:

• x m/sec = x × 18/5 km/hr.
