Agent Orange: Friendly fire that keeps on burning. | In the days before calculators, extra long division and multiplications was a lot more painful than now. Since we're only concerned with proportionality here, it's extra work to multiply by Pi and then turn right around and divide by the same number. Try working your numbers without using Pi, or just use a 1 instead of 3.1416. Bet you'll come out with the same thing. |
