The diameter of earth is approximately 13,000 km. Which distance is closest to the length of its radius
Mhhh, isn't the radius just half the diameter???
The radius of a sphere is half of its diameter. Since the diameter of the Earth is approximately 13,000 km, the radius would be half of this, which is 6,500 km.
To find the length of the radius of Earth, we need to divide the diameter by 2 since the radius is half of the diameter. Let's calculate it.
Length of radius = Diameter / 2
Length of radius = 13,000 km / 2
Length of radius = 6,500 km
So, the length of the radius of Earth is approximately 6,500 km.
Now, let's find which distance is closest to the length of Earth's radius. Here are a few options to consider:
1. 5,000 km: This distance is shorter than the length of Earth's radius, so it is not closest to the radius.
2. 6,000 km: This distance is also shorter than the length of Earth's radius, so it is not closest to the radius either.
3. 6,500 km: This distance is exactly the same length as the radius of Earth, making it the closest to the radius.
4. 7,000 km: This distance is longer than the length of Earth's radius, so it is not closest to the radius.
Therefore, the distance that is closest to the length of Earth's radius is 6,500 km.
