Yuliya22 [10]

Answer:

48cm

Step-by-step explanation:

Can y’all tell me what all numbers are rational or irrational
murzikaleks [220]

The irrational numbers among these given are:

\sqrt{83}, 24\pi, 90.790170..., \sqrt{109}

The remaining numbers are all rational.

<h3>What are rational and irrational numbers?</h3>

  • Rational numbers are numbers that can be represented by fractions, such as terminating decimals.
  • Irrational numbers are numbers that cannot be represented by fractions, such as non-terminating decimals and non-exact roots.

The irrational numbers in this problem are:

  • Square root of 83, as it is a non-exact root.
  • 24π, as π is a non-terminating decimal.
  • 90.790170, which is a non-terminating decimal.
  • Square root of 109, as it is a non-exact root.
