Since we are dealing with volume, when one object is 4 times bigger than another, the difference in volume is 4^3 = 64.
6 cm sphere = 4/3 *PI * 6^3
6 cm sphere = 4/3 *PI * 216
6 cm sphere =
<span>
<span>
<span>
904.78 cc
24 cm sphere = </span></span></span>4/3 *PI * 24^3
24 cm sphere = 4/3 *PI * 13,824
24 cm sphere =
<span>
<span>
<span>
57,905.84
</span>
</span>
</span>
cc
Comparing the volumes: <span>57,905.84 / 904.78 = </span><span><span><span>64

Answer:
37.36%
Step-by-step explanation:
Each year it increases 1.6%.
So year 1 it increases (1+1.6%), year 2 increases (1+1.6%)^2 and so on...
so after 20 years, overall increase is found by 1.016^20 = 1.3736 or increase of 37.36%
please give thanks :)
