A chord Is shaped into a circle whose radius is 15 cm. It is then reshaped to a square. Find its side.
To find the side length of the square, we need to consider the relationship between the chord and its corresponding arc in the circle.
The chord of a circle is perpendicular to the radius passing through its midpoint. Thus, when a chord is reshaped into a square, one side of the square will be equal to the length of the chord.
Given that the radius of the circle is 15 cm, the length of the chord is twice the radius, or 2 * 15 cm = 30 cm.
Therefore, the side length of the square is 30 cm.
