Question

1) find the the length of tangent
to a circle to radius 4 cm from a point on the concentric circles of radius 6cm​

Answer 1

Step-by-step explanation:

Steps of construction:

• Draw two concentric circles with radii 4 cm and 6 cm.
• Draw the radius OP of the bigger circle.
• Make a perpendicular bisector of OP which intersects OP at point O'.
• Taking O′P as radius, draw another circle.
• From point P, draw tangents PQ and PR; as shown in the figure.
