1 answer

Let the radius of the cylinder be r units.

Given that the height is 2 times the radius, the height = 2r units.

The lateral area of a cylinder is given by the formula: Lateral area = 2πrh, where r is the radius and h is the height.

Given lateral area = 16π, we have:
16π = 2π(r)(2r)
16π = 4πr^2
4 = r^2
r = √4
r = 2 units

Therefore, the length of the radius of the cylinder is 2 units.
