Question

estimate values of expressions with pi
what is the circumference of a circle with a diameter of 3.25 meters? estimate the circumference
to the hundredths place using 3.14 for π. (1 point)
10.21 meters
33.18 meters
10.22 meters
10.2 meters

Explanation:

Step1: Recall the formula for circumference

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

Step2: Substitute the given values

Given \(d = 3.25\) meters and \(\pi=3.14\), we substitute into the formula: \(C=3.14\times3.25\).

Step3: Perform the multiplication

Step4: Round to the hundredths place

Rounding \(10.205\) to the hundredths place (the second decimal place). The digit in the thousandths place is \(5\), so we round up the hundredths digit. \(10.205\approx10.21\)

Answer:

10.21 meters
