Question

A length of glass tubing is 10 cm long. What is its length in inches to the nearest inch?

Answer 1

3.93701 inches exactly or to the nearest inch is 4 inches

Answer 2

Answer:

$4\ in$

Step-by-step explanation:

we know that

$1\ in =2.54\ cm$

so

By proportion

Convert $10\ cm$ to inches

$\frac{1}{2.54}\frac{in}{cm}=\frac{x}{10}\frac{in}{cm}\\ \\x=10/2.54\\ \\x=3.94\ in$

Round to the nearest inch

$3.94\ in=4\ in$
