Question

after stepping into a room with unusual lighting, shannons pupil has a diameter of 2 millimeters. what is the pupils circumference? if necessary, round your answer to the nearest hundredth. millimeters submit

Explanation:

Step1: Recall the formula for circumference

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

Step2: Substitute the given diameter

Given \(d = 2\) millimeters. Substitute into the formula: \(C=\pi\times2\).
Using \(\pi\approx3.14159\), we get \(C = 2\times3.14159=6.28318\).

Step3: Round to the nearest hundredth

Rounding \(6.28318\) to the nearest hundredth (two decimal places). The third - decimal digit is \(3\lt5\), so we keep the second - decimal digit as it is.

Answer:

\(6.28\)
