Answer:
Step-by-step explanation:
Given
volume of the Venus = 9.4 x 10^11 km^3
The volume mars is approximately = 1.6 x 10^11km³
A) In order to know how many times as great as the volume of mars is the volume of Venus, we take the ratio of volume of Venus to volume of mars.
Ratio = volume of Venus/volume of mars
Ratio = 9.4 x 10^11 km³/1.6 x 10^11km³
Ratio = 9.4/1.6
Ratio = 5.875
Ratio = 5.9(to the nearest tenth)
Hence the volume of venus is approximately 5.9 great as volume of mars.
B) If volume of earth is approximately 0.69 x 10^-1 times larger than the volume of mars, then the amount by which earth is greater than mars is expressed as:
0.69 x 10^-1 × volume of mars
= 0.69 x 10^-1 × 1.6 x 10^11.
= 1.104×10^{-1+11}
= 1.104×10^10
Volume of earth will be 1.104×10^10+1.6 x 10^11.
Volume of earth = 0.1104×10^11+1.6 x 10^11.
Volume of earth = 1.7104×10¹¹ km³
Hence the approximate volume of earth is 1.7104×10¹¹km³
