Question

A truck wheel makes 12000 revolutions in moving 24.4km distance.find the circumference of wheel​

Answer 1

Correct Question:

• A truck wheel makes 12000 revolutions in moving 26.4km distance.find the circumference of wheel

Answer :

• The circumference of wheel is 70cm

Given :

• A truck wheel makes 12000 revolutions in moving 24.4km distance

To find :

• Circumference of wheel

Solution :

Given ,

• Number of revolutions is 12000
• Distance travelled is 24.4km

24.4km = 2440000

Now ,

• Distance travelled/Number of revolutions

Then,

》2440000/12000

》 220cm

As we know that,

• Circumference = 2πr

• Truck distance travelled in revolutions = circumference

》2πr = 220

》2 × 22/7 × r = 220

》r = 220/2 × 7/22

》r = 35

Now we have to find the circumference of wheel

As we know that,

• Diameter = 2r

》 2(35)

》70cm

Hence , The circumference of wheel is 70cm
