The diameter of the sun is about 1,391,000 kilometers, and the diameter of Venus is about 12,100 kilometers. About how many times larger is the diameter of the sun than the diameter of Venus?
A.
1.15 × 102
B.
1.4 × 107
C.
1.15 × 103
D.
1.4 × 106
B. 1.4 x 10^7
To find out how many times larger the diameter of the sun is than the diameter of Venus, you would divide the diameter of the sun by the diameter of Venus:
1,391,000 km / 12,100 km = 115.0834710744
Rounded to the nearest whole number, the diameter of the sun is approximately 115 times larger than the diameter of Venus. In scientific notation, this is 1.15 x 10^2 which is equivalent to 1.15 x 100.
Therefore, the correct answer is B. 1.4 x 10^7.
