<u>Answer:</u> The correct answer is option A.
<u>Explanation:</u>
To calculate the volume of an object, we use the formula:
We are given:
Density of an object = 
Mass of an object = 8.2 grams
Volume of an object = ?
Putting values in above equation, we get:
Hence, the correct answer is Option A.
Meteorologists also use satellites to observe cloud patterns around the world, and radar is used to measure precipitation. All of this data is then plugged into super computers, which use numerical forecast equations to create forecast models of the atmosphere.
