Question

a circle of sunflowers is planted in springfields central park. the circle has a radius of 1 yard. what is the circles circumference? if necessary, round your answer to the nearest hundredth. yards

Explanation:

Step1: Recall the formula for circumference

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

Step2: Substitute the radius value

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

Step3: Calculate the value

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

Step4: Round to the nearest hundredth

Rounding \(6.28318\) to the nearest hundredth (two - decimal places), we look at the third decimal digit. The third decimal digit is \(3\lt5\), so we keep the second decimal digit as it is. So \(C\approx6.28\).

Answer:

\(6.28\)
