@jhonyy9 Think you could help me work through this one? :D

jhonyy9 · Answer

volum of A = area of base time height 

V_A = 144pi *6 = 864pi in^3

V_B = 648pi in^3

864 ----- 100%
648 ----- x%
-------------------

  x = 648*100 /864 = 75%

then this mean that 100% -75% =25% what is that volum B is smaller with 25% than 
volum A
