Answer:
49
Step-by-step explanation:
Because the volume of a rectangular prism is 
, where l is length, w is width, and h is height, then 
. Dividing both sides by 4, we have 
. Dividing both sides by 4 again, we have 
. Now, dividing both sides by 11, we have 
The length of the radius of the cylinder is 2 units.
The lateral surface area of a cylinder = <span>
2πrh</span>
where, r = base radius
h = height of cylinder
Now, height of cylinder = 2r units
⇒ 16 π = 2×π×r×<span>h
</span>⇒ 16 π = 2×π×r×2r
⇒
= 4
⇒ r = 2 units
Thus, radius is 2 units.
