16

Step-by-step explanation:

1. Find diameter of circle:

   If her shirt is 10 inches wide and she wants to leave 1in off of each side, that    

   means she wants the diameter of her circle to be 8in.

   10 - 1 - 1 = 8in

2. Solve for Area:

   (Area of circle = )

   To find area we need to find Radius

   (Radius = diameter/2)

    Radius = 8/2 = 4in

3. Plug radius into equation to get

    = 16

7

step-by-step explanation:

the answer would be 7
