| September 11, 2021 | education
The radius of the circle is known from the condition and it is equal to R = 0.5 cm. And also the value of the constant is pi = 3.14.
We need to find the length of a given circle.
In order to find the circumference of a circle, we will use the following formula.
l = 2пR, where R is the radius of the circle, and the number pi is given to us in the condition.
Substitute the known values into the formula and calculate the circumference:
l = 2 * 3.14 * 0.5 = 1 * 3.14 = 3.14 cm.
So, the length of a circle with a radius of R = 0.5 cm is 3.14 cm.
Answer: The circumference is 3.14 cm.
