Ive noticed a mistake in the question by the way. Where it says 3.29 1030kg, 3.33 1020m and 2.17 108 years it is supposed to say 3.39 x 10^30 kg, 3.33 x 10^20 m and 2.17 x 10^8. Keep trying please I think this may be a uni type of question.

Pllllease help me I have been stuck on this for ages: [HRW5 14-57E] A star, with mass 3.29 1030 kg, revolves about the center of the Milky Way galaxy, which is 3.33 1020 m away, once every 2.17 108 years. Assuming that each of the stars in the galaxy has a mass equal to that of our star...

So could someone please tell me what the hell the answer is. Thankso:)
