In the given figure, ABCD is a square inscribed in a circle of radius 4 cm. CD is produced till point E. From E a tangent is drawn to the circle at point B.  What is the length (in cm) of AE?

In triangle ABC, F is the centroid. If AB=11 cm, BC=14 cm and AC=7 cm, then what is the value (in cm) of EF?

In the figure below, O of the circle is the centre. OA = 3 cm, AC = 3 cm and OM is perpendicular to AC. So the value of ∠ABC will be
