Question

estimate values of expressions with pi quick check
what is the circumference of a circle with a diameter = 4 feet? which of the following is the best estimation for the circumference? (1 point)
13 feet
50 feet
25 feet
6 feet

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 value of diameter

Given \(d = 4\) feet. Using \(\pi\approx3.14\), then \(C=\pi\times4\approx3.14\times4 = 12.56\) feet.

Answer:

13 feet
