Answer:

see below

Step-by-step explanation:

A = pi r^2

If they have the same radius they have the same area

A two circles = pi r^2 +pi r^2

                      = 2 pi r^2

If we double the radius

A = pi (2r)^2

   = pi 4r^2

The combined area of two circles is  1/2  the area as the area of a circle with twice the radius.
