To find the radius of the cone, we can use a formula for the volume of a cone: V = (1/3)πr^2h, where V is the volume, π is a constant (approximately 3.14159), r is the radius, and h is the height. Given that the height of the cone is 12 and the volume is not provided, we cannot directly solve for the radius using this formula. Thus, the correct answer cannot be determined with the given information.
