Question

the radius of a circle is 1 centimeter. what is the circles circumference? round your answer to the nearest hundredth. centimeters

Explanation:

Step1: Recall the formula for circumference

The formula for the circumference \( C \) of a circle is \( C = 2\pi r \), where \( r \) is the radius.

Step2: Substitute the radius value

Given \( r = 1 \) cm, substitute into the formula: \( C = 2\pi(1) = 2\pi \).

Step3: Calculate the numerical value

Using \( \pi \approx 3.14159 \), we get \( C \approx 2\times3.14159 = 6.28318 \).

Step4: Round to the nearest hundredth

Rounding \( 6.28318 \) to the nearest hundredth gives \( 6.28 \).

Answer:

\( 6.28 \)
