Question

what is the circumference of a circle with a radius of 2.5 feet? estimate the circumference to the tenths place using 3.14 for π. (1 point) 15.6 feet 16 feet 7.85 feet 15.7 feet

Explanation:

Step1: Recall the formula for circumference

The formula for the circumference of a circle is \(C = 2\pi r\).

Step2: Substitute the given values

Given \(r = 2.5\) feet and \(\pi=3.14\), we substitute into the formula: \(C=2\times3.14\times2.5\).
First, \(2\times2.5 = 5\), then \(C = 5\times3.14\).

Step3: Calculate the result

\(5\times3.14=15.7\)

Answer:

15.7 feet
