Answer:

A. 16.86 square inches

Explanation:

Area of Circle =
\pi r^2, where r = radius.

Area of Rectangle =
l * w, where l = length and w = width.

We are given the radius of the circle as 1, and we use π as 3.14


  • 3.14*1^2

  • 3.14*1

  • 3.14

Next, we find the area of the rectangle.


  • 5*4

  • 20

Lastly, we subtract 3.14 from 20.


  • 16.86

Therefore, the answer is A. 16.86 square inches.
