Steps of construction :
1. Take a point O at a distance of 3.8 cm from AB and with O as centre draw a circle of radius 1.3 cm.
2. With O as centre and radius equal to 4.7 cm, draw an arc cut BA at P. Draw PX perpendicular to AB.
3. Produce AO to cut the circle at C and join CP cutting the circle at D.
4. Join OD and produce it to cut PX at S. With S as centre and radius = SD, draw the circle PDR. This is the required circle.
