2pi r=123.2
r=123.2/2×3.14
r=19.6
Area =pi rsquare
Area =3.14×19.6×19.6
Area =1206.2624
r=123.2/2×3.14
r=19.6
Area =pi rsquare
Area =3.14×19.6×19.6

circumference=2*22/7*r
=123.2=44/7r
r=123.2*7/44
=11.2*7/4
=78.4/4
=19.6
now are pie r square
22/7*19.6*19.6
=1207.36
=123.2=44/7r
r=123.2*7/44
=11.2*7/4
=78.4/4
=19.6
now are pie r square
22/7*19.6*19.6
=1207.36
