Suppose the area of a circle with radius r r is larger than the area of a square with side length l l. define a formula that expresses d d, how much greater the area of a circle with radius r r is than the area of a square with side length l l, in terms of r r and l l. (that is, write a formula that expresses d d in terms of r r and l l.)

Reid Bass · Answer 1

We know that the area of any circle is Ac = πr**2The area of the square is As = l**2

If we substract the Areas, we can know the difference between them

d = πr**2 - l**2
