Answer:

Step-by-step explanation:
From the question we are told that:
Radius 
Height 
Rate 
Surface Radius 
Generally the equation for Volume is mathematically given by

Since radius to height ratio gives



Therefore


Generally the equation for Change of Volume is mathematically given by





12 * 4 = 48
25 * 4 = 100
48/100 = 0.48, or 48%
12 is 48% of 25
