area of shaded portion = 49.5 yd²
____________________
Step-by-step explanation:
radius of circle = 5 yd ------ ( given )
height of triangle = 16 yd --- ( given )
base of triangle = 16 yd ----- ( given )
area of triangle = 1/2 × base × height
= 1/2 × 16 × 16
= 128 yd²
area of circle = π × radius²
= 3.14 × 5 × 5 --- ( π = 3.14 )
= 78.5 yd²
---------------------------------------
area of shaded portion = area of triangle - area of circle
area of shaded portion= 128 yd²-78.5 yd²
area of shaded portion = 49.5 yd²
