The figure shown is a right circular cylinder with a radius of $r$ and height of $h$. A second right circular cylinder (not shown) has a volume that is $392$ times as large as the volume of the cylinder shown. Which of the following could represent the radius $R$, in terms of $r$, and the height $H$, in terms of $h$, of the second cylinder? 

 

Difficulty: Hard
A: 

$R= 8r$ and $H = 7h$

B: 

$R= 8r$ and $H = 49h$

C: 

$R=7r$ and $H = 8h$

D: 

$R = 49r$ and $H = 8h$
