1.
area of shaded portion = pie R^2 - pie r^2
= pie (28^2 - 7^2)
solve it by using
pie = 22/7
2.area of shaded portion=
area of square - are of circle
=side^2 - pie r^2
= 8^2 - pie r^2
= 64 - pie (8/2)^2
=64 - pie 16
use pie = 22/7
and get ur another answer

1.Area shadeed portion=Area of outer -area of inner
πr^2-πr^2
π{(28)^2-(7)^2}
π{784-49}
π(705)
22/7×705
Area shadeed portion=2,215.71429cm^2
2.
Area shadeed portion=area of square-area of circle
a^2-πr^2
(8)^2-22/7(4)^2
64-22/7(16)
64-352/7
448-352/7
96/7
Area shadeed portion=13.71cm^2
