Question

Answer

This is a Area question.

1. Area of quadrant = 1/4 × pi × 14 × 14 = 49 pi

2. Area of triangle = 1/2 × 14 × 14 = 88

3. Area of half eyeball = 49 × 22/7 – 88 = 154 – 88 = 66

4. Area of shaded region = 8 × 66 = 528

 

😊

Note

Area of half eyeball = quadrant  – triangle 

Area of boomerang = square – quadrant
