D=21cm
R=21/2=10.5
So, Area of the circle =pie r sq.
=22/7*10.5*10.5
= 346.5 CM sq.
D=14cm
R=14/2 = 7cm
So, Area Of the circle =pie r Sq.
= 22/7*7*7
=154 cm sq.
D=7cm
R=7/2=3.5
So, Area of the circle = pie r sq.
=22/7*3.5*3.5
= 38.5 cm sq.
R=21/2=10.5
So, Area of the circle =pie r sq.
=22/7*10.5*10.5
= 346.5 CM sq.
D=14cm
R=14/2 = 7cm
So, Area Of the circle =pie r Sq.
= 22/7*7*7
=154 cm sq.
D=7cm
R=7/2=3.5
So, Area of the circle = pie r sq.
=22/7*3.5*3.5
