19)Earth's diameter is about 3 2/3 time that of the moon. How do their volumes compare?
Re: I have no idea how to do these
where r is the radius, d is the diameter and pi is approximately 3.141592.
Since the volume is obtained by multiplying the cube of the radius by some factor,
it can be inferred that the volumes of two solids are proportional to the cubes of their radii or diameters (Since diameter= 2(radius)).
Therefore, the earth's volume would be
times the volume of the moon.
is approximately 49.3.
Similarly, since sun's diameter is approximately 110 times that of earth's,
the volume of the sun would be (110x110x110) times that of the earth, that is 1331000 times!
