Question

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. $1.15 \times 10^3$
b. $1.15 \times 10^2$
c. $1.4 \times 10^7$
d. $1.4 \times 10^6$

Explanation:

Step1: Set up division ratio

$\frac{\text{Sun's diameter}}{\text{Venus's diameter}} = \frac{1,391,000}{12,100}$

Step2: Simplify the division

$\frac{1,391,000}{12,100} \approx \frac{1,3910}{12.1} \approx 115$

Step3: Convert to scientific notation

$115 = 1.15 \times 10^2$

Answer:

B. $1.15 \times 10^2$
