With what speed must a satellite be moving in order to maintain a
circular orbit 3360 km above the surface of the earth?

Explanation:

Since we are told the satellite movs in a circular orbit,  we can use the equation of velocity in the case of uniform circular motion:

Where:

is the velocity of the satellite

is the Gravitational Constant

is the mass of the Earth

is the radius of the orbit

Solving with the given data:
