Find the area of the shaded portion of the figure. Each vertex of square ABCD is at the center of a circle. Leave your answers in terms of π (pi)

Please, give me some minutes to take over your question
______________________________
You can calculate the shaded area = ABCD area - a circle area ( they are four fours of a circle with diameter = 2 in)
________________________________
Can you see the updates?
______________________________
ABCD area = 2*2 = 4 in^2
________________________
The circle area = π * (r^2)
diameter = 2*r
r= 1
The circle area = π * (r^2)
The circle area = π * (1^2)
The circle area = π *1
The circle area = π in^2

Answer
The shaded area = 4 - π ( in^2)
