Area of 1st semi circle = πr²/2 π (3)²/2π9/2 or 9π /2Area of 2nd semi circle = πr²/2π(3)²/2π9/2 or 9π/2Area of 1st semi circle + Area of 2nd semi circle9π/2 +9π/2 =9π
Area of big semi circle = πr²π (6)²/π 36
Area of shaded region = 36π - 9π = 27π If you like my way to answer plzzz upvote and do follow me !!!!!!!
