Answer:

The diameter would be 16

Step-by-step explanation:

The area of a circle is a=[tex]r^{2}[/tex]×π. Now just plug in the values you have which is you area. 201=[tex]r^{2}[/tex]×π now divide by pi on both sides you that you get about 64=[tex]r^{2}[/tex]. Now find the square root on both sides which will then give you 8 as your radius. To find diameter from radius you have to multiply by 2. 8*2=16
