2r = diameter of the circle.
Diameter of the circle = side of the square
since the adjacent sides of the squares are at 90 degrees, the diagonal = \(2r\sqrt{2}\)
This is because a 90-45-45 triangle will be formed between 2 sides of the square and the diagonal
now simplify
option A is:
\(2r\sqrt{2}\)
option B is:
\(\frac{5r}{2}\)
cancel r from both sides, then multiplying both sides by 2 we get,
option A = \(4\sqrt{2}\)
option B = 5

If it does not mention in the question how do we deduce that r is the radius or side or diagonal.
