Question

The radius of a circle of well is1.75m.How many revolution will it make in travelling 11 km. ​

Answer 1

Given:

Radius = 1.75 m

Distance traveled = 11 km

To Find:

The number of revolutions

Solution

Find the circumference:

Circumference = 2πr

Circumference = 2π(1.75)

Circumference = 3.5π

Circumference = 11 m

Find the number of revolutions:

Total distance traveled = 11 km

Total distance traveled = 11 000 m

One revolution = circumference

One revolution = 11 m

Number of revolution = 11 000 ÷ 11

Number of revolution = 1 000

Answer: 1000 revolution

Answer 2

Answer:

1000 revolution...........
