Answer 1

Answer:

★Total Shaded Area = 69.66 cm² ★

Step-by-step explanation:

Given:

• A circle is drawn under a Square
• Side of Square is 18 cm
• Diameter of circle will also be 18 cm

To Find:

• Total shaded area

Solution : Shaded Area = Area of Square – Area of the Circle

→ Area of Square= (Side)² = (18)² = 324cm²

( Radius of circle will be D/2 = 18/2 = 9

→Area of Circle = πr² = 3.14 x (9)²

→ 3.14 x 81

→254.34 cm ²

Therefore, Shaded Area = (324–254.34) cm² = 69.66 cm²
