A circle of radius 2 cm is drawn using both 0.5 cm graph paper and 2 mm graph paper.

To find the area using graph, we need to count the number of squares inside the circle in each case.

For squares which are not entirely inside, we use the following

1. If less than half of the square is inside, we ignore 2. if more than half of a square is inside, we count it as one.

In the first figure, area of one square is 0.5 x 0.5 = 0.25 cm² In the second figure, area of one square is 0.2 0.2 = 0.04 cm
