May you help me on this problem, please?
I know it is not 2:1 .

Answer 1

calculate the volume using the formula
v=(4/3)πr² for each then compare to find the ratio

Answer 2

4! :D
I really thought it was 4:1 !! :DD

Answer 3

\[r _{1}=\frac{ 18 }{ 2 }=9 inch,r _{2}=\frac{ 9 }{ 2 } inch\]
\[\frac{ V _{1} }{ V _{2} }=\frac{ \frac{ 1 }{ 3 } \pi r _{1}^3}{ \frac{ 1 }{ 3 }\pi r _{2} ^3}=\frac{ r _{1} ^3}{ r _{2} ^3}\]

Answer 4

so in case of hat A r= 9 in case of hate B r=4,5

you know area =pir^2

hat A has area 81pi and hat B area 18,5pi

ratio of the volum supposed that are the same height will be ratio 81/18,5 = ?

Answer 5

18.5 you mean?
If so, that would =4.378

Answer 6

\[\frac{ V _{1} }{ V _{2} }=\frac{ 9^3 }{ \left( \frac{ 9 }{ 2 } \right)^3 }=\frac{ 9^3 }{ 9^3 }\times2^3=\frac{ 8 }{ 1 }\]

Answer 7

4,5 squared = 20,25 will be right ---- sorry

Answer 8

so
\[V _{1}:V _{2}=8:1\]

Answer 9

so my opinion is 4:1

Answer 10

What!?? Why are you putting commas?
Also, why is everyone getting different answers!?? 4:1, 8:1, 2 ..

@ganeshie8 I need your help!
