Calculate the circumference, the diameter of which is 10cm; 2.5m.
| July 13, 2021 | education
To solve these problems, you need to remember the formula for finding the circumference:
L = π * d,
where π = 3.14;
d is the diameter of the circle.
Let’s use the above formula and solve the tasks:
if d = 10 cm, then we get the expression:
L = 3.14 * 10 = 31.4 (cm).
If d = 2.5 m, then the circumference will be:
L = 3.14 * 2.5 = 7.85 (m).
Answer: for d = 10 cm, the circumference is 31.4 cm; with d = 2.5 m, the circumference is 7.85 m.
