Answer

$10\text{ cm}\approx 3.94\text{ in}$

Work Step by Step

If want to convert from centimeters to inches, we have to consider the following conversion rate: $2.54 \text{ cm}= 1 \text{ in}$ By dividing both sides by $2.54$, we get: $1\text{ cm}= \frac{1}{2.54} \text{ in}$ We mulitply both sides by 10 in order to get the answer to the question: $10\text{ cm}= \frac{10}{2.54} \text{ in}\approx 3.937\text{ in}$ By rounding it to two decimal places: $10\text{ cm}\approx 3.94\text{ in}$
