Question
The Diameter of the moon is approximately one fourth of the diameter of the earth. What fraction of the volume of the earth is the volume of the moon?
The correct answer is: 1/64
Explanation:
- We have given the diameter of moon is approximately one fourth of the diameter of the earth.
- We have to find the fraction of the volume of the earth is the volume of the moon
Step 1 of 1:
Let the diameter of moon be ,Then the diameter of earth will be 4d
So, Radius of moon will be . And the radius of earth will be
Since, both earth and moon are sphere
We can use formula of volume of sphere .
And volume of earth will be
Therefore, the fraction will be
Therefore, the fraction will be
