1. ## radians word problem--help me out plzz

a weather satellite completes a circular orbit around the world every 3h. the satellite is 2500 km above the earth, and the radius of the earth is approxiamtely 6400 km. how far does the satellite travel in 1 min, to the nearest km?.....

2. What sort of attempt have you made so far? and post it so we may help you.

3. ## i did not try

i tries a lot of method
but nothing works,....

How many degrees in a circle?
You should say 360.

How many minutes in 3 hours?
You should say 180.

If the satellite completes one orbit in 3 hours,
then it is moving 2 degrees of arc per minute of time.

2 degrees is equal to $\dfrac{2 \pi}{180} \, = \, \dfrac{pi}{90}$ radians.

What is the radius of the satellite?
You have the numbers to determine that.

Then a simple multiplication gives the answer you seek.
Does that help?
