Answer:
Area of shaded region is 30.5 cm²
Step-by-step explanation:
by Pythagoras formula
DB²=AD² + AB²
DB²=6²+8²
DB²=100
DB=10 cm
therefore
radius of circle is 5 cm
now area of circle is
Ac=pi×r²
=3.14×5²
=78.5
area of rectangle is
Ar=l×b
=8×6
=48
area of shaded portion = area of circle - area of rectangle
=78.5-48
=30.5 cm²
