The Area of a Japanese Circle

The formula for the area of a circle is pi times the square of its radius. The Japanese government has evacuated an area around the Fukushima power plants with a radius of 40km, or 5,024km sq.

The U.S. evacuation circle therefore has an area of 20,096km sq. That’s a discrepancy 15,072km size.

This discrepancy is the reason that this year’s U.S. JETs haven’t been told their placements yet. We were supposed to have been informed in May, but some placements fall into this gray area.
