Question

the diameter of a circle is 120 in. find the circumference to the nearest whole number.

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 \(d = 120\) in. Substitute \(d\) into the formula: \(C=\pi\times120\).

Step3: Calculate the value

Using \(\pi\approx3.14159\), then \(C\approx3.14159\times120 = 377.0\) (rounded to the nearest whole number).

Answer:

\(377\) in.
