Question

the round base of a copper tea kettle has a diameter of 18 centimeters. what is the bases circumference?
if necessary, round your answer to the nearest hundredth.
centimeters

Explanation:

Step1: Write the formula for circumference

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

Step2: Substitute the value of diameter

Given \(d = 18\) cm. Substitute into the formula: \(C=\pi\times18\).

Step3: Calculate the value

Using \(\pi\approx3.14159\), then \(C = 3.14159\times18= 56.54862\).

Step4: Round to the nearest hundredth

Rounding \(56.54862\) to the nearest hundredth (two - decimal places), we look at the third decimal digit. Since \(8\gt5\), we round up. So \(56.54862\approx56.55\).

Answer:

\(56.55\)
