| August 6, 2021 | education
A circle is a flat geometric figure whose points are equidistant from a given point, the center of the circle.
Let’s write the formula for calculating the circumference:
l = 2 π R,
where l is the circumference, R is the radius, π = 3.14.
Substituting the values of the radius of the circle R and the constant π into the formula, we find the length of the circle, l:
l = 2 × 3.14 × 5 = 31.4 cm.
Answer: The circumference is 31.4 cm.
