Question

estimate values of expressions with pi quick check
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)
10.22 meters
10.21 meters
33.18 meters
10.2 meters

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 \(d = 3.25\) meters and \(\pi=3.14\), then \(C=3.14\times3.25\).

Step3: Perform the multiplication

Step4: Round to the hundredths place

Rounding \(10.205\) to the hundredths place gives \(10.21\).

Answer:

10.21 meters
