Question

Radius of circular wheel is 17.5 .How many revolution will it make in 11 km

Answer 1

One revolution is equal to the circumference of a circle. C=2πr tells us a 35cm circle has a circumference of 219.91cm. Which is 2.1991 meters.

Dividing 33,000 meters by 2.1991 is 15006.14 revolutions.

Answer 2

It will make 100 revolutions in 11 km

Step-by-step explanation:

Radius of circular wheel = 17.5 m

Circumference of wheel = 2 \pi r = 2 \times \frac{22}{7} \times 17.5=110 m

So, Distance traveled in 1 revolution = 110 m

No. of revolution done in covering 110 m = 1

So,No. of revolution done in covering 11 km(=11000 m) = \frac{1}{110} \times 11000=100

Hence it will make 100 revolutions in 11 km
