The velocity of a satellite in orbit around the Earth can be calculated using the following formula:

v = √(G * M / r)

where:
v = velocity of the satellite
G = gravitational constant (6.67408e-11 N m^2 kg^-2)
M = mass of the Earth (5.972 x 10^24 kg)
r = distance from the center of the Earth to the satellite (6.4 x 10^6 m)

Plugging in the values, we get:

v = √(6.67408e-11 N m^2 kg^-2 * 5.972 x 10^24 kg / 6.4 x 10^6 m)
v ≈ 7.85 km/s

So, the velocity of the satellite is approximately 7.85 km/s.
