Question

draw a circle of radius 3 cm. from a point p,7 cm away from its centre draw two tangents to the circle. measure the length of each tangent

Answer 1

Draw a circle with radius 3 cm and centre O.

Draw a line segment OP = 7 cm
Make perpendicular bisector of OP which intersects OP at point O’.
Take O’P as radius and draw another circle.
From point P, draw tangents to points of intersection between the two circles.

=7²-3²
= 49-9
=40

∴PQ=PR=40cm

IF IT IS CORRECT..PLEASE GIVE ME A BRAINLIEST!!

Answer 2

1. Draw a line segment PO = 7 cm.

2. From the point O, draw a circle of radius = 3 cm.

3. Draw a perpendicular bisector of PO. Let M be the mid-point of PO.

4. Taking M as centre and OM as radius draw a circle.

5. Let this circle intersects the given circle at the point Q and R.

6. Join PQ and PR.

On measuring we get

PQ = PR = 6.3 cm
