Question

4. The radius of a circular wheel is 1.75 m. How many revolutions will it make in travelling 11 km​

Answer 1

Answer:

1000 revolutions....

Step-by-step explanation:

as to know the total revolution

we have to get the circumference of the circular wheel

therefore circumference of the circular wheel is

$2\pi r$

2 X 22/7 X 1.75

= 11m

now to get revolution we have to convert it into km

therefore,

11 m = 0.011 km

now revolution = 11 km ÷ 0.011 km

= 1000 revolutions
