Respuesta :

diameter = 2 * radius
= 2*2
= 4 inches

Hence, diameter is 4 inches

Step-by-step explanation:

The correct answer is 4.

The diameter of a circle (and a semicircle) is always twice as long as its radius.

So, if the radius is 2, then the diameter is [tex]\bf{2\times2=4\:inches}[/tex].

∴ The diameter is 4 inches.
