The area of the circle is the amount of space on the circle
The area of the circle is about 14 cm²
How to estimate the area of the circle?
From the question, we understand that the circle fits perfectly into the grid.
This means that the area of the circle is about the same with the area of the square grid.
The area of the square grid is:
Area = 4 * 4
Evaluate
Area = 16
The surrounding areas are triangles with the following estimated dimensions:
Base = 1.5, Height = 1.5
The area of the four triangles is:
Area = 4 * 0.5 * 1.5 * 1.5
This gives
Area = 4.5
Subtract the area of the triangle from the square
Remaining area = 16 - 4.5
Remaining area = 11.5
Approximate
Remaining area = 12
Hence, the area of the circle is about 12 cm²
How to improve the grid?
To improve the grid, we simply get the actual dimension of the black region
