a circle has a radius of 4.5 cm which measurment is closest to the circumfrenceof the circle in cm

Answer 1

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.
