Answer: 2.26cm^2approx.
Step-by-step explanation: In the right angle triangle
AB is the height
BC is the base
Area of triangle=1/2×Height×Base
=1/2×6×10
=3×10
=30cm^2
Radius of circle= Height/2
=6/2
=3
Area of circle=πr^2
=3.14×3^2
=3.14×9
=28.26cm^2 approx.
Area of shaded region= 30 - 28.26
=2.26cm^2approx.
