Calculate the circumference of a circle if its radius is 10 m and 15 m.
| May 22, 2021 | education
When calculating the circumference, the formula is used: l = πd, where π = 3.14, d is the diameter of the circle.
If the diameter is 10 m, then the length will be: 3.14 * 10 = 31.4 (m).
If the diameter is 15 m, then the value of the circumference will be: 3.14 * 15 = 47.1 (m).
Answer: a circle with a diameter of 10 m has a length of 31.4 m, and a circle with a diameter of 15 m has a length of 47.1 m.
