Question

Here is a figure made of a circle inscribed in a square.

If the sides of the square are 12 m

(a) What is the area of the square?                   

(b) What is the area of the circle, rounded to 2 decimal places?            

(c) What is the area of the blue section?                   

Hint: The area of a square, with side s, is 

Area of a circle with radius r is 

Answer 1

area of the square = 12^2 = 144 m^2

area of circle = pi(r)^2 = about 3.14159(6)^2 = 113.10 m^2

area of the blue section = area of the square minus area of the circle = 144-113.10 = 30.90 m^2
