Answer:
D is the correct answer
Step-by-step explanation:
cylinder volume equation: v=[tex]\pi[/tex][tex]r^{2}[/tex]h
Water heater x= [tex]\pi[/tex](8.5)^2 x 48= 10895.04
Water heater y= [tex]\pi[/tex] (9.5)^2 x 44= 12475.26
Water heater z= [tex]\pi[/tex] (10.5)^2 x 32= 11083.54
A is false because water heater Y has the greatest volume
B is false because all the volume are different
C is false because z has the smallest volume
