Solve the following question:

Question: In January 2006, astronomers reported the discovery of a planet comparable in size to the earth orbiting another star and having a mass of about 5.5 times the earths mass. It is believed to consist of a mixture of rock and ice, similar to Neptune. Take mass of earth = 5.97 x 10²⁴ kg and radius of Earth = 6.38 x 10⁶ m.

Part A- If this planet has the same density as Neptune (1.76g/cm³), what is its radius expressed in kilometer?

Please show all work and clearly explain to find the radius. Thanks.
