| Determine the radius of the circle if the circumference is 1.57 m.

The circumference is calculated by the formula: l = 2 Пr, where П is a constant equal to 3, 14; r is the radius.

From here we calculate the radius of the circle: r = l / 2 P.

Now let’s plug the known data into the formula.

r = 1.57 / 2 * 3.14.

r = 1, 57/6, 28.

r = 0.25 m.

Answer: the radius of the circle is 0.25 meters.
