उत्तर
Steps of construction:
1) Draw a circle with centre O and radius equal to 3 cm.
2) Draw a diameter AC
3) Draw another diameter BD which bisects AC at right ∠s.
4) Join AB, BC, CD and DA.
5) Now draw tangents to the given circle at the points A, B, C, D and let them meet at P, Q, R, S. Then PQRS is the required square about the given circle.
