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

`4\ in`

Explanation:

we know that

`1\ in =2.54\ cm`

so

By proportion

Convert
`10\ cm` to inches

`(1)/(2.54)(in)/(cm)=(x)/(10)(in)/(cm)\\ \\x=10/2.54\\ \\x=3.94\ in`

Round to the nearest inch

`3.94\ in=4\ in`
