Answer:
4
Explanation:
The diameter of a circle is 2 times the radius. (the diameter is the length from an outer point in the circle, to one directly across)
In this case, the radius is 2.
So, 2 x 2 = 4.
The diameter is 4.
4 in
The diameter of a circle is twice its radius. Here the given radius is 2 in.
So diameter = 2 in × 2 in = 4 in
Radius = Diameter/2
Diameter = Radius × Radius
