- $2\sqrt{2} - 1$
- $\frac{(2\sqrt{2} - 1)}{2}$
- $\frac{(3\sqrt{2} - 1)}{2}$
- $\frac{(2\sqrt{2} - 1)}{3}$
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Using circle symmetry and chord proportionality, coordinates yield DH length as $\frac{2\sqrt{2} - 1}{2}$.
\[
\boxed{\frac{2\sqrt{2} - 1}{2}}
\]

- Rekha drew a circle of radius 2 cm on a graph paper of grid 1 cm × 1 cm. She then calculated the area of the circle by adding up only the number of full unit-squares that fell within the perimeter of the circle. If the value that Rekha obtained was 4 sq cm less than the correct value, then find the minimum possible value of \(d\).
