The approximate diameters of Uranus and Mercury are listed below:
Uranus: 5, point, 1, 1, times, 10, to the power 45.11×10
4
kilometers
Mercury: 4, point, 8, 8, times, 10, cubed4.88×10
3
kilometers
How much greater is the diameter of Uranus? Express your answer using either standard notation or scientific notation.
To find the difference in diameters between Uranus and Mercury, we subtract the diameter of Mercury from the diameter of Uranus:
Uranus diameter: 5.11 x 10^4 km
Mercury diameter: 4.88 x 10^3 km
Difference = (5.11 x 10^4) - (4.88 x 10^3)
= 51,100 km - 4,880 km
= 46,220 km
Therefore, the diameter of Uranus is 46,220 km greater than the diameter of Mercury.
