Radius of a circle is $6 \mathrm{cm}$. The lengths of some chords are $4 \mathrm{cm}, 6 \mathrm{cm}, 10 \mathrm{cm}$ and $8 \mathrm{cm}$ respectively. Write the major segments corresponding to these chords in increasing order of area.

Radius of a circle is $6 \mathrm{cm}$. In the circle the length of chord is $12 cm$, then what kind of relation will you find between major segment and minor segment?

Identify radius, chord, diameter, sector and segment in given figure and write in the table:
