Answer:
1st option
Explanation:
the area of the shaded portion is calculated as
area of sector - area of white Δ
area of sector = area of circle × fraction of circle
= πr² ×
( r is the radius )
= π × 8² ×

= 64π ×

= 16π in²
area of Δ =
bh ( b is the base and h the perpendicular height )
here b = h = 8
area of Δ =
× 8 × 8 =
× 64 = 32 in²
then
area of shaded portion = (16π - 32 ) in²
