a circle has a radius of 4.5 cm which measurment is closest to the circumfrenceof the circle in cm
The circumference of a circle can be calculated using the formula:
Circumference = 2 * π * radius
Given that the radius of the circle is 4.5 cm, we can substitute this value into the formula:
Circumference = 2 * π * 4.5
Using π as approximately 3.14, we can calculate the circumference:
Circumference ≈ 2 * 3.14 * 4.5
Circumference ≈ 28.26 cm
Therefore, the closest measurement to the circumference of the circle is approximately 28.26 cm.
