Question

the diameter of a circle is 16 kilometers. what is the circles circumference? round your answer to the nearest hundredth. kilometers submit

Explanation:

Step1: Recall the formula for the circumference of a circle

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

Step2: Substitute the given diameter into the formula

We are given that the diameter \( d = 16 \) kilometers. Substituting this into the formula, we get \( C=\pi\times16 \).

Step3: Calculate the value and round to the nearest hundredth

Using the approximation \( \pi\approx3.14159 \), we have \( C = 16\times3.14159=50.26544 \). Rounding this to the nearest hundredth (two decimal places), we look at the third decimal place which is 5. When the third decimal place is 5 or more, we round up the second decimal place. So \( 50.26544\approx50.27 \).

Answer:

50.27
