Answer:
The answer to your question is the letter B. 27
Step-by-step explanation:
Data
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
Answer:
Step-by-step explanation:
You don't need to simplify 4/7 because you can't divide 4 and 7 to a same number. I don't necessarily know what you mean by simplifying.
