Question

what is the circumference of a circle with a diameter of 3.75 kilometers? estimate the circumference to the hundredths place using 3.14 as π. (1 point)
44.18 kilometers
12 kilometers
11.79 kilometers
11.78 kilometers

Explanation:

Step1: Recall the formula for circumference

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

Step2: Substitute the given values

Given \(d = 3.75\) kilometers and \(\pi=3.14\), we substitute into the formula: \(C=3.14\times3.75\).

Step3: Perform the multiplication

Step4: Round to the hundredths place

Rounding \(11.775\) to the hundredths place. The digit in the thousandths place is \(5\), so we round up the hundredths digit. \(11.775\approx11.78\).

Answer:

11.78 kilometers
