Question

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

Explanation:

Step1: Recall circumference formula

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

Step2: Substitute the diameter value

Given \( d = 16 \) millimeters, substitute into the formula: \( C=\pi\times16 \).

Step3: Calculate and round

Using \( \pi\approx3.14159 \), we get \( C = 16\times3.14159 = 50.26544 \). Rounding to the nearest hundredth (two decimal places), we look at the third decimal place (5). Since 5 ≥ 5, we round up the second decimal place: \( 50.27 \).

Answer:

50.27
