Answer 1

Answer:

When a circle is inscribed in a square, the length of each side of the square is equal to the diameter of the circle. That is, the diameter of the inscribed circle is 8 units and therefore the radius is 4 units. The area of a circle of radius r units is A=πr2 . Substitute r=4 in the formula.

Answer 2

thats simple.

the area of the circle would be A-πr²

because the area of the square is A and the circle is within the square, so to find it's area we need to subtract it with that of the square. we can denote it a variable also

so if I say that the area of the circle=x then the formula would be A-x
