Question

With the help of compass ,draw the circles of the following radii. Mark their radius and diameter. Write steps of construction (b) 7.2cm

Answer 1

Answer:

Answer

Given: Diameter=9cm

Radius=

2

9

=4.5cm

1.Mark a point O.Draw a circle of radius 4.5cm.

2.From the point mark a point P such OP=7.5cm

3.Draw tangents PT and PR from the point P such that it touches the circumference of the circle.

∴ Length of the tangents PT=6cm and PR=6cm

Answer 2

Answer:

Given: Diameter

=

9

cm

Radius

=

2

9

=

4.5

cm

1. Mark a point O .Draw a circle of radius 4.5 cm.

2.From the point mark a point P

such

OP=

7.5

cm

3.Draw tangents PT and PR from the point P such that it touches the circumference of the circle.

∴Length of the tangents

PT=

6

cm and

PR=

6

cm
