| February 12, 2021 | education
A circle is a flat geometric figure whose points are equidistant from a given point, the center of the circle.
The formula for finding the circumference is as follows:
l = 2πR,
where l is the circumference, R is the radius of the circle, π = 3.14.
Substituting the radius constant π into the formula, we calculate the circumference:
l = 2 × 3.14 × 3 = 18.84 cm.
Answer: The circumference is 18.84 cm.
