The area of the circular base of a cylinder is 36π square units. The height of the cylinder is 2 units.What is the lateral area of the cylinder? Express the answer in terms of π.

The base area is πr² = 36π, so r² = 36 and the radius is 6 units. The lateral area is the circumference of the base times the height: 2πrh = 2π(6)(2) = 24π square units, which is choice B.
