round your answer to the nearest hundredth.
kilometers
submit

Explanation:

Step1: Recall circumference formula

The formula for the circumference \( C \) of a circle is \( C = \pi d \), where \( d \) is the diameter.

Step2: Substitute the diameter value

Given \( d = 2 \) kilometers, substitute into the formula: \( C = \pi \times 2 \).

Step3: Calculate and round

Using \( \pi \approx 3.14159 \), we get \( C \approx 2 \times 3.14159 = 6.28318 \). Rounding to the nearest hundredth gives \( 6.28 \).

Answer:

6.28
