The velocity of a satellite rotating around the Earth

[yashboi123]

Homework Statement

A satellite travels at an altitude of 6580 km where gravity is 9.2 m/s^2.

Relevant Equations

v^2/r = a

Not sure what r would be in this scenario. I tried adding the radius of the earth to the altitude but that wasn't correct either.

 

[Bandersnatch]

It looks like r is just the 'altitude'.

Please show your work. We cannot help you if you don't tell us what you did.

The confusion is in the question itself.

If gravity is 9.2 m/s^2 (as stated in the question), then satellite distance from earth center is 6580km (verify yourself!). And that distance should not be called altitude :-(

If altitude is really 6580km, g is about 2.38 m/s^2.
