Answer:
Step-by-step explanation:
first we need to get the side length of a square.
Area of a square A = L²
1 = L²
L = √1
L = 1 unit
The shaded portion is a circle.
Area of a circle = πd²/4
The diameter of the circle = 4L = 4(1) = 4units
Substitute into the formula;
A =πd²/4
A = π(4)²/4
A = 4(3.14)
A = 12.56inits²
B) The area of the whole shape = Length * width
Length = 6
Width = 6 (6 squares)
Area of the shape = 6*66 = 36units²
Percentage of the area shaded = 21.56/36 * 100
Percentage of the area shaded = 2156/36
Percentage of the area shaded = 59.9%
