Question

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

Explanation:

Step1: Recall the formula for circumference

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

Step2: Substitute the given radius

Given \( r = 1\) foot. Substitute into the formula: \( C=2\pi\times1\).

Step3: Calculate the value

Using \(\pi\approx3.14159\), then \(C = 2\times3.14159\times1=6.28318\).

Step4: Round to the nearest hundredth

Rounding \(6.28318\) to the nearest hundredth (two - decimal places). The third decimal digit is \(3\lt5\), so \(C\approx6.28\).

Answer:

\(6.28\)
