Question

a circle with diameter 6 cm​

Answer 1

Step-by-step explanation:

Place the ruler on a rough paper. Now take the sharp end of the compass and place it on the paper adjacent to “0cm” on the ruler. 3)Now drag the other arm of the compass with the pencil to place the tip of the pencil adjacently to 3cm on the scale. (Diameter = 6cm, so radius = 3cm ).

Answer 2

b

Step-by-step explanation:

) AB is the diameter of circle

i.e., AB = 6 cm

and OA is the radius of circle

= (1/2) of diameter = 6/2 = 3 cm

i.e. OA = OB = 3 cm

(ii) AB is the diameter of circle

i.e., AB = 8.4 cmand OA is the radius of circle

= 1/2 of diameter = 8.4/2 = 4.2 cm

i.e. OA = OB = 4.2 cm.
