Step-by-step explanation:
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.
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

⇒ r = 2 units
Thus, radius is 2 units.
