Unformatted text preview: Correct answer: 209 . 868 cm. Explanation: We can convert to inches and then to centimeters: 6 ft 10 5 8 in = p 6 ft Â· 12 in 1 ft + 10 . 625 in P Ã— 2 . 54 cm 1 in = 209 . 868 cm . 003 10.0 points The mass of the planet Saturn is about 5 . 64 Ã— 10 26 kg and its radius 6 Ã— 10 7 m. Calculate its density. Correct answer: 623 . 357 kg / m 3 . Explanation: Let : M = 5 . 64 Ã— 10 26 kg and R = 6 Ã— 10 7 m . Assuming Saturn to be a sphere (neglecting the rings), V = 4 3 Ï€ R 3 , so the density of Saturn is Ï = M V = M 4 3 Ï€ R 3 = 3 (5 . 64 Ã— 10 26 kg) 4 Ï€ (6 Ã— 10 7 m) 3 = 623 . 357 kg / m 3 ....
