Question

draw a circle of diameter 6 cm . mark the centre o. draw a diameter PQ and a radius OA. measure their length and compare them.​

Answer 1

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 :-

( Diagram in attachment )

• Diameter = 6cm
• radius = D / 2 = 6/2 = 3cm

➙ Difference = 6-3 = 3cm

• What is circle ?

➙ A circle is a shape consisting all points in a plane that are at a given distance from a given point the centre .

• Area = πr²
• perimeter = 2πr
• diameter = 2r
• radius = d/2
