Question

A lawn roller makes 20 revolution in 1 hour. The radians it run through in 25 minuted

Answer 1

Answer: The radians it run through in 25 minutes is 50/3pi radian.

Step-by-step explanation:

1 revolution= 2*pi radian

Given that

The number of revolution in 1 hour= 20

So,

The number of revolution in 25 minutes= 20x25/60=25/3

The radians it run through in 25 minutes= (25/3)2*pi

=> (50/3)*pi

Answer 2

Answer:

50π/3 radian

Step-by-step explanation:

I revolution = 360º = 2π radians

Find the number of revolutions in 25 mins:

1 hour = 20 revolutions

1 min = 20 ÷ 60 = 1/3 revolution

25 mins = 1/3 x 25 = 25/3 revolutions

Find the radian:

I revolution = 2π radians

25/3 revolutions = 2π x 25/3 = 50π/3 radian

Answer: It would have gone 50π/3 radian
