Answer:

Multiply the radius or diameter by 2.

Step-by-step explanation:

Because there is no drawing, I will tell you what to do. A scale factor means multiply all the dimensions by [some number]. The scale factor is 2, so you will need to multiply the radius or diameter by 2.

Let radius of the circle be r

Radius of circle scaled by scale factor 2 is 2r

let the equation of the circle be center at (0,0)

[tex]x^{2} +y^{2} =r^{2}[/tex]

The equation for the circle with radius 2r is (0,0)

[tex]x^{2} +y^{2} =4r^{2}[/tex]

The diagram for the circles is attached  below.
