Answer:
Approximately 20037.929 km.
Step-by-step explanation:
The circumference of Mars can be calculated using the formula for the circumference of a circle:
Circumference = 2 * π * radius
Since we are given the equatorial circumference of Mars, which represents the maximum circumference around its equator, we can divide this value by 2π to obtain the radius.
Equatorial circumference = 2 * π * radius
20000 km = 2 * π * radius
To find the radius, we rearrange the equation:
radius = 20000 km / (2 * π)
Using the approximate value of π as 3.14159, we can calculate the radius:
radius ≈ 3183.0988618379067 km
Now that we have the radius, we can calculate the circumference using the formula:
Circumference = 2 * π * radius
Circumference ≈ 2 * 3.14159 * 3183.0988618379067 km
Circumference ≈ 20037.929 km
Therefore, the approximate circumference of Mars, based on its equatorial circumference of 20000 km, is approximately 20037.929 km.
