<u>We are given</u>
- Radius of Earth; 6.4 x 100 meters = 640 meters
Clearly, the shape of the earth is a sphere. Thus, to determine the volume of the earth, we will use a formula that determines the volume of a sphere.

When we substitute the radius in the formula, we get;


Take π as 3.14


Simplify the numerator;


Divide the numerator by 3;


Example:
378 • 123= x
Start- 378. Then 378. 378. 378
With- •123 ->do. •100 ->•020 -> •003
Then add the answers of the three problems. 37800+ 7560+1134
Which then you will have the answer.
Answer:
32.064
Step-by-step explanation:
You can model a percent many ways. Compare fractions, decimals and percents using area models. You can also use a pi chart, bar graph, and so many other graphs when using percentages. Hope this helps you.
