Question

A circle is drawn within a square as shown. What is the best approximation for the area of the shaded region? Use 3.14 to approximate pi.

Answer 1

Area of the square:
A ( square ) = 10² = 100
Area of the circle:
A ( circle ) = 5² π = 25 · 3.14 = 78.5
Area of the shaded region:
A = 100 - 78.5 = 21.5
Answer:
A ) 21.5 cm²
