Answer:
shaded area = 17.38 cm²
Step-by-step explanation:
given:
diameter of circle = 18 cm and = side of square
π = 3.142
shaded area = ( Area of square - Area of circle ) x 1 / 4
Area of square = s² = 18² = 324 ²cm
Area of circle = π d² / 4
= 3.142 (18²) / 4
= 254.5 cm²
therefore, shaded area = ( 324 cm² - 254.5 cm² ) * 1/4
= 17.38 cm²
