The correct answer is: $11.811023622\text{ in}$

Explanation

To convert centimeters to inches use the exact relation $1\text{ in}=2.54\text{ cm}$. Divide the length in cm by 2.54 to get inches.

Steps:

  1. Relation: $1\text{ in}=2.54\text{ cm}$
  2. Convert: $30\text{ cm}\times\frac{1\text{ in}}{2.54\text{ cm}}=\frac{30}{2.54}\text{ in}$
  3. Compute: $$\frac{30}{2.54}\approx11.811023622\text{ in}$$

Therefore, $30\text{ cm}\approx11.81\text{ in}$ (rounded to two decimal places).
