The Radius of large sphere = 3 times the size of the radius small sphere.
The Ratio of Volume = ?
Formula
Volume of a sphere = 4/3 πr³
Process
1.- Calculate the volume of the large sphere
Vl = 4/3 π(3r)³
2.- Calculate the volume of the small sphere
Vs = 4/3 πr³
3.- Calculate the ratio
Vl / Vs = [4/3π(3r³)] / [4/3 πr³]
- Simplification
Vl / Vs = 3³r³ / r³
Vl / Vs = 27
