Question

A circle has a radius of 4.5 centimeters. Which measurement is closest to the circumference of the circle in centimeters?

Answer 1

[AI-generated answer — Bot GPT 3.5]

The circumference of a circle can be calculated using the formula:

Circumference = 2 * radius * π

Substitute the radius given (4.5 cm) into the formula:

Circumference = 2 * 4.5 cm * π
Circumference = 9 cm * π

To find an approximate decimal value for π, you can use 3.14.

Circumference ≈ 9 cm * 3.14
Circumference ≈ 28.26 cm

Therefore, the closest measurement to the circumference of the circle in centimeters is 28.26 cm.
