Question

Draw any circle on the graph paper. Count the squares and use them to estimate the area of the circular region.
Figure

Answer 1

This circle on the squared paper consists of 21 complete squares, 15 more than half squares and 8 less than half squares.
Let us assume that the area of 1 square is 1 cm².
If we neglect the less than half squares while approximating more than half square as equal to a complete square, we get:
Area of this shape = (21 + 15) = 36 cm²
