Question

What is the order of magnitude of the length of a pencil in inches

Answer 1

1

Explanation:

Length of pencil = 19 cm

`1\ cm=0.393701\ in`

`\\\Rightarrow 19\ cm=19* 0.393701\ in\\\Rightarrow 19\ cm=7.480319\ in`

A number written in the form
`m* 10^n` then the number n denotes the order of magnitude of that number. The value of m lies between the values

`(√(10))/(10)\leq m < √(10)\\\Rightarrow 0.316\leq m<3.16.`

So,

`7.480319=0.7480319* 10^(1)`

Hence, the order of magnitude of the length of a pencil in inches is 1

Answer 2

0 (Zero)

Explanation:

What is the average length of a pencil?

The length of a pencil is arround 19.05 centimeters or 7.5 inches. The diameter is 5/16 inch or 7.9 mm. The volume is 10 um 3. so that is why the magnitude of the length of a pencil is zero.
