Chapter 9, Problem 1E

To determine

To calculate:To write the area of Arctic Ocean in scientific notation −

Ocean	Area $\left(k{m}^2\right)$
Pacific	$156,000,000$
Atlantic	$77,000,000$
Indian	$69,000,000$
Southern	$20,000,000$
Arctic	$14,000,000$

Answer to Problem 1E

The correct option is $B.$ $1.4\times {10}^7$

Explanation of Solution

Given information:

Table :

Ocean	Area $\left(k{m}^2\right)$
Pacific	$156,000,000$
Atlantic	$77,000,000$
Indian	$69,000,000$
Southern	$20,000,000$
Arctic	$14,000,000$

Formula Used:

Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between $1$ and $10$ is multiplied by a power of $10$ .

Calculation:

Given −

Table as

Ocean	Area $\left(k{m}^2\right)$
Pacific	$156,000,000$
Atlantic	$77,000,000$
Indian	$69,000,000$
Southern	$20,000,000$
Arctic	$14,000,000$

Using the above explanation, we have area of the Arctic Ocean as −

  $14,000,000=1.4\times {10}^7$

Thus, the area of the Arctic Ocean is $1.4\times {10}^7$ $k{m}^2$ .

Conclusion:

The correct option is $B.$ $1.4\times {10}^7$
