Final answer:
To convert the Earth's diameter from centimeters to kilometers, divide by 100,000. The Earth's diameter of 1.3 x 10⁹ centimeters is equal to 13,000 kilometers.
Step-by-step explanation:
The question is asking to convert the diameter of the Earth from centimeters to kilometers. Given that the Earth's diameter is 1.3 x 10⁹ centimeters, we start by recognizing that 1 kilometer is equal to 100,000 centimeters (cm). Therefore, to convert centimeters to kilometers, we divide the number of centimeters by 100,000.
Performing the division, we get: 1.3 x 10⁹ cm ÷ 100,000 cm/km = 1.3 x 10⁹ cm × 1 km / 100,000 cm = 13,000 km.
Therefore, the Earth's diameter in kilometers is 13,000 km.
The diameter of the Earth can be calculated by converting the given value of 1.3 x 10⁹ centimeters to kilometers. To do this, divide the given value by 100,000 to convert centimeters to kilometers.
So, the Earth's diameter in kilometers is:
1.3 x 10⁹ cm ÷ 100,000 = 1.3 x 10⁴ km
Therefore, the Earth's diameter is 1.3 x 10⁴ kilometers.
