Question 217367: The circumference of the world is 25,000 miles and there is a band placed around it. To the band is added 10ft and moved off the earth at an equal distance of x. Which is the largest that can walk under the band. Using C=6.28R. Can a bee 1 inch tall, a snake 1 ft tall, a 3ft child or a 6ft adult walk under the band?

The circumference of the world is 25,000 miles and there is a band placed around it. To the band is added 10ft and moved off the earth at an equal distance of x. Which is the largest that can walk under the band. Using C=6.28R. Can a bee 1 inch tall, a snake 1 ft tall, a 3ft child or a 6ft adult walk under the band?
:
Actually you can do this easily
10%2F6.28 = 1.59 ft; enough for the snake and the bee
;
Prove this using the given values
:
Add 10' to the circumference
25000 + 10%2F5280 = 25000.0018939394 mi
Find the difference the in radii with the circumferences
25000.0018939394%2F6.28 - 25000%2F6.28 * 5280 = 1.59'
