Hello!
If all of the dimensions are multiplied by 3, the volume will also be multiplied by 3.
Our answer is A) 3.
I hope this helps!
We know the formula for volume of cylinder of given by
V = π r² h
If the dimensions are tripled, new volume will be :-
V' = π (3r)² (3h) = π (9r²) (3h) = 27 π r² h = 27 V
We can see new volume is 27 times original volume.
