The distance you have stated is the circumference of the Earth at average ground level. Can you calculate the average radius if you know the circumference? (Answer: yes.)
A different circumference, measured 3 feet above the one at ground level, would have a different radius.
If you know that new radius, you can calculate the new circumference.
Circumference = (2)(pi)(r)
Hello Becca:
The ideal equater is a circle, and you have its circumference.
Substitute that given value into the formula for circumference, and then solve for the radius.
Next, add 3 to the radius (to obtain the radius of the larger circle), and then use the same formula to calculate the larger circle's circumference.
Please show your work.
Also, take a moment to read the forum guidelines; you may begin with this link to the summary page.
