Question

the diameter of a circle is 72 meters. what is the circles circumference? round your answer to the nearest hundredth. meters submit

Explanation:

Step1: Recall circumference formula

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

Step2: Substitute the diameter value

Given \( d = 72 \) meters, substitute into the formula: \( C=\pi\times72 \). Using \( \pi\approx3.14159 \), we get \( C\approx3.14159\times72 \).

Step3: Calculate the result

\( 3.14159\times72 = 226.19448 \). Rounding to the nearest hundredth (two decimal places), we look at the third decimal digit (4), which is less than 5, so we keep the second decimal digit as is. Thus, \( C\approx226.19 \).

Answer:

226.19
