Find the circumference of the diameter 14 dm.
| February 12, 2021 | education
The formula for finding the circumference looks like this: L = 2 * pi * r. Where pi is a constant number equal to 3.14 (rounded to hundredths), r is the radius of the circle. Let us substitute 14 decimetres in the formula instead of the radius and find the length of this circle. We get: L = 2 * pi * r = 2 * pi * 14 = 9 * pi = 28 * 3.14 = 87.92 decimeters.
Answer: 87.92 decimeters.
