Question

1. find the circumference of a circle if the diameter is 5 inches.

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 value of diameter

Given \(d = 5\) inches. Substitute \(d=5\) into the formula \(C=\pi d\). So \(C = 5\pi\) inches. Using \(\pi\approx3.14\), we get \(C\approx5\times3.14 = 15.7\) inches.

Answer:

The circumference of the circle is approximately \(15.7\) inches.
