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. A. 21.5 cm² B. 78.5 cm² C.100 cm² D.178.5 cm² Circle inscribed inside a square with outside shaded, one side labeled 10 cm

Answer 1

21.5

Explanation:

i took the test so i know 100%

Answer 2

Area of the square:
A 1 = 10² = 100 cm²
Area of the circle:
A 2 = 5² π = 25 · 3.14 = 78.5 cm²
Area of the shaded region:
A = A 1 - A 2 = 100 - 78.5 = 21.5 cm²
Answer: A ) 21.5 cm²
