Question

The radius of the earth is 3963 mi.
The latitude of Durham, North Carolina is 36 degrees North. About how far is Durham from the North Pole?

Answer 1

you'll want to find the circumference of the earth...you know the earth is 360 degrees round...so you have 90 from the equator to the north pole...

Answer 2

Circumference is equal to the radius times 2 times pi

Answer 3

90 minus 36 gives you the degrees you have left to go
3963 times 2 is 7926
times that by pi and you get 24900
if you divide 24900 by 4 (like 360 divided by 4 = 90) then you'll get the distance of 90 degrees around the earth

Answer 4

or 6225 miles in 90 degrees

to change that to 54 degrees
6225 times 54 divided by 90
and that should be your answer

Does that help?

Yes! Thank you so much!
