A student needs to make a circular cardboard piece with an area between 154 square inches and 616 square inches. The function f(

Nezavi [6.7K]

The area of the circle by definition is given by:
$f (r) = \pi * r ^ 2
$
For f (r) = 154:
$154 = \pi * r ^ 2
$
Clearing r we have:
$r ^ 2 = 154 / 3.14

 r = \sqrt{154/3.14} 

 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:
7 <r <14
