Answer:

A = 4pi mm^2  or approximately 12.56 mm^2

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

We know the radius is 2

A = pi 2^2

A = 4 pi mm^2

We can approximate pi by 3.14

A = 4*3.14

A =12.56 mm^2

12.57. To get a circle’s area you use the formula πr^2. This makes it π2^2, which equals 12.57. Hope this helps :)
