Sometimes 8th grade math assignments are unintentionally humorous. Today’s:
Find the volume of each cone. Round the answer to the nearest tenth. (use π = 3.14).
In other words, after telling students to round π to 3 digits of precision, answers with 6 digits of precision were sought. The answer sheet had “Volume =” prompts rather than “Volume ≈” (a wavy “approximately equal” sign, in case it doesn’t render correctly on your browser).
- Kansas has 10 digits of precision in its child support calculation system (a plaintiff suing someone who earned $1 trillion per month would be able to calculate monthly child support profit of more than $362 million to the nearest dime)
