Which of the following uses the correct formula to find the approximate circumference of a circle that has a radius of 12? Use 3.14 for π and express your answer to the hundredths place.(1 point) Responses 18.84 18.84 452.16 452.16 37.68 37.68 75.36

Answer 1

To find the circumference of a circle, you can use the formula:

$$C=2\pi r$$

where $C$ is the circumference, $\pi$ is approximately 3.14, and $r$ is the radius.

Given that the radius $r$ is 12, we can substitute that into the formula:

$$C=2\times 3.14\times 12$$

Calculating that step-by-step:

1. Calculate $2\times 3.14=6.28$
2. Then multiply that result by 12:

$$C=6.28\times 12=75.36$$

So the approximate circumference of the circle is 75.36.

The correct response is 75.36.
