Question

What is the area of the given circle if each grid measures 1 sq cm?

• A. 20 sq cm
• B. 10 sq cm
• C. 14 sq cm
• D. 16 sq cm

Answer 1

The correct option is D 16 sq cm

In the figure given,
Area occupied by each grid/square is 1 sq cm.
Number of squares occupied by the circle:
Full squares = $6$
Half squares = 0
More than half portion of the square = $10$
Less than half portion of the square = $4$

So,
$\text{area}=6\times 1+10\times 1+4\times 0=16\text{sq cm}$
