1) The formula for finding the area of a circle: S = pi * r squared (where pi is a constant number equal to 3.14 (rounded to hundredths), r is the radius of the circle);
2) Substitute in the formula instead of the radius the decimal fraction 2.5 meters and find the area of the circle: S = pi * 2.5 * 2.5 = 6.25 * 3.14 = 19.625 square meters.
Answer: 19.625 square meters.
