Question

The radius of a circle is 6 kilometers. What is the circle's circumference?

r=6 km
Use ​ ≈ 3.14 and round your answer to the nearest hundredth.

Answer 1

The circumference of a circle with a 6-kilometer radius is approximately 37.68 kilometers when rounded to the nearest hundredth, using the approximation π ≈ 3.14.

Step-by-step explanation:

The circumference of a circle is calculated using the formula C = 2πr, where C is the circumference and r is the radius. Given that the radius of the circle is 6 kilometers, we can substitute this value into the formula as follows:

C = 2π(6 km) = 12π km

Using the approximation π ≈ 3.14, we can calculate the circumference:

C ≈ 12 * 3.14 km ≈ 37.68 km

Rounding this result to the nearest hundredth, the circumference of the circle is approximately 37.68 kilometers.
