Will it be true to say that the perimeter of the square circumscribing a circle of radius $$a$$ cm is $$8a \,cm ?$$ Give reasons for your answer.
Report Question
0%
True
0%
False
Explanation
Side of square = Diameter of circle
$$\therefore AB = 2a$$
So, the perimeter of square
$$= 4 \times AB$$
$$= 4 \times 2a$$
$$= 8a \,cm$$
Hence, the given statement is true.
What will be the area of the largest square that can be cut out of a circle of radius.

$$400\, cm^2$$
Explanation
Given, radius of circle $$= 10\, cm$$
The diagonal of the square will be equal to the diameter of the circle.
Now, in right-angled triangle $$DAB$$,
$$\Rightarrow (BD)^2 = (AD)^2-(AB)^2$$
$$\Rightarrow (20)^2 =x^2+x^2$$
$$ \Rightarrow 2x^2=400$$
$$ \Rightarrow x^2 =200$$
Therefore, $$200\, cm^2$$ is the area of the largest square.
The side of a square is $$10\,cm$$ then its perimeter is:

$$30\,cm$$
Explanation
Given side of square $$a = 10\ cm$$
Perimeter of square :
$$= 4\times a$$
$$= 4\times 10 \ cm $$
$$=40 \ cm$$
Distance between two dots is $$1\,cm$$
