37°34'51.22"N, 108°48'4.59"W - circular fields in the midwest. Use the
tools to find the area. The "pac-man" shaped piece - What's the area?
How did you find it? Crop yield per acre of corn is 130 bushels...
what's the yield for the area?

24°10'3.12"N, 23°27'43.80"E - more circular fields in Libya. A famous
oasis.

Washington monument in D.C. - trig, pythagorean theorem. Find the shadow
length, know the height, find the angle/hypotenuse - when was the photo
taken?
