The rectangle will be positioned such that the diagonal of the rectangle will become the diameter of the circle. This is true as the triangle in a semi circle with diameter as the base makes a 90 degree at the circumference.
Thus, the diameter of the circle = \(\sqrt{3^2+4^2}\) = 5 ---> Circumference = \(\pi\) d = 5\(\pi\). C is the correct answer.
