very good solution !chisigma said:[sp]Let suppose that the side of the square is 2. In this case, if x is the radius of the 'small circle', for the theorem of Pythagoras it must be...
$\displaystyle (1-x)^{2} + 1 = (1+x)^{2}$
... so that is $\displaystyle x = \frac{1}{4}$...[/sp]
Kind regards
$\chi$ $\sigma$
The formula for calculating the radius of a small circle is: r = √(A/π) where r is the radius and A is the area of the circle.
The radius of a small circle is smaller than the radius of a larger circle. It is the distance from the center of the circle to any point on the circumference and is typically measured in centimeters or inches.
A compass or a ruler can be used to measure the radius of a small circle. A protractor can also be used to measure the angle of a small circle, which can then be used to calculate the radius.
The diameter of a small circle is twice the length of its radius. This means that if the radius of a small circle is 5 cm, the diameter would be 10 cm.
Knowing the radius of a small circle is important in various fields such as engineering, architecture, and physics. It is used to calculate the area, circumference, and other properties of a circle, which can be applied in designing structures, measuring distances, and understanding the motion of objects.
