Physics Problem Satellites in Circular Orbits: What is the orbital speed of the second satellite? - satellite

A satellite is made known in a circular orbit around a planet. The satellite has a speed of 1.70 X 10 (at power 4) m / s, and the radius of the orbit is 5.25 x 10 (6 energy) meters a second satellite has a speed to move around this planet. The path of the second satellite has a radius of 8.60 x 10 (6 power) m. What is the speed of the second satellite?
