| March 30, 2021 | education
To make it more familiar and convenient to count, let’s translate decimeters into centimeters: (4 dm is equal to 40 cm). You can calculate the circumference using the following formula: L = πD = 2πr,
r is the radius of the circle;
D is the diameter of the circle, which we have is 40 centimeters;
L is the circumference;
π- 3.14.
Now you can calculate: 3.14 * 40 = 125.6.
Answer: The length of this circle is 125.6 centimeters.
