Nezavi [6.7K]
The area of the circle by definition is given by:
 f (r) =  \pi  * r ^ 2&#10;
 For f (r) = 154:
 154 =  \pi  * r ^ 2&#10;
 Clearing r we have:
 r ^ 2 = 154 / 3.14&#10;&#10; r =  \sqrt{154/3.14} &#10;&#10; r = 7
 For f (r) = 616:
 616 = \pi * r ^ 2
 Clearing r we have:
 r ^ 2 = 616 / 3.14 r = \sqrt{616/3.14} r = 14
 Answer:
 
a reasonable domain for f (r) is:
