Question

Which real world problem is most likely to involve irrational numbers

Answer 1

Real world problems involving measurements or geometrical calculations are most likely to involve irrational numbers. For example, finding the length of the diagonal of a square whose side length is 1 meter, or calculating the circumference of a circle with a radius of 3 meters would involve the use of pi, an irrational number. Another example would be determining the height of a skyscraper using trigonometry, which could involve the use of trigonometric ratios that involve irrational numbers.
