In order to find to find the length of a circle with a given radius R = 0.8 cm, we need the value of the constant – the number n and it is 3.14.
Let’s remember the formula for finding the circumference.
It looks like this:
l = 2пR, where l is the circumference, R is the radius of the circle.
Let’s plug the known values into the formulas and find the circumference.
l = 2 * 3.14 * 0.8 = 6.28 * 0.8 = 5.024 = 5.02 cm.
So, now we can say that the circumference with a given radius R = 0.8 cm is 5.02 cm.
Answer: the circumference is 5.02 cm.
