| January 11, 2021 | education
The formula for the circumference: C = 2 * n * R, where C is the circumference, R is the radius of the circle.
We substitute the data into the formula: C = 2 * 3.14 * 3 = 6 * 3.14 = 18.84 cm.
Let’s round the result to tenths, since the number 4 is in hundredths, then we round down: 18.8 | 4 = 18.8 cm.
Answer: The circumference is 18.8 cm.
