Given data:
Radius of larger raindrop,

Radius of typical cloud droplet,

Since, r1=100r2. Therefore,

The volume is given as,

Therefore, the volume of the large raindrop is,

The volume of the typical cloud is,

Taking ratios of the volume,

Substituting all known values,

Therefore, the volume of the large raindrop equals 10^6 times the volume of a typical cloud droplet.
