Question

C. Draw a circle of diameter 9 cm. Name its centre A, diameter CD and
radius AB​

Answer 1

Answer:

STEP 1:

Take a point on your paper and mark it as A. This will be the centre of your circle.

STEP 2:

From A, draw a line to any point on the circumference of the circle.

Extend this line on the opposite side. You will get a line that goes through the centre and meets opposite points on the circumference. This is the diameter. Label the points of the diameter as C and D.

STEP 3:

From centre A, draw a line to the circumference but do not extend it. This is your radius. Label the point on the circumference as B.

NOTE:

The length of the diameter is twice the length of the radius, and the length of all radii (multiple radius) is always equal.

So,

AB=AC=AD,

and CD=2AC=2AD=AB.

I have attached a rough diagram with this so you get some clarification on how your figure would look.
