Answer:

See below.

Step-by-step explanation:

The side of the square is k.

The area of the square is k².

The diameter of the circle is k.

For a circle, radius = diameter/2.

The radius of the circle is k/2.

Formula for area of circle: A = πr².

Here, the radius, r, is k/2.

The area of the circle is π(k/2)² = (πk²)/4

The shaded area is the difference between the area of the square and the area of the circle.

shaded area = k² - (πk²)/4

We are told that the shaded area = A

A = k² - (πk²)/4

Multiply both sides of the equation above by 4.

4A = 4k² - πk²
