Answer:
30.89cm³
Step-by-step explanation:
Given that:
Side length, s of square = 12cm
Area of square = s² = 12² = 144cm²
Since the circle touches the edge of tbe square, then the diameter of the circle = side length of square = 12 cm
Area of a circle = πr²
Radius, r = diameter / 2 = 12/2 = 6cm
A = 3.142 * 6^2
A = 3.142 * 36
A = 113.112 cm²
Area of shaded portion = area of square - area of circle
= 144cm² - 113.112cm³
= 30.89cm³
40960000
