the radius of a circle is 6.9 in. find the circumference to the nearest whole number.
answer attempt 1 out of 2
c = in submit answer

Explanation:

Step1: Write the formula for circumference

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

Step2: Substitute the value of radius

Given \(r = 6.9\) in. Substitute \(r = 6.9\) into the formula: \(C=2\pi\times6.9\).

Step3: Calculate the value

\(C = 2\times3.14\times6.9=43.332\) (using \(\pi\approx3.14\)).

Step4: Round to the nearest whole number

Since \(43.332\approx43\) (as the decimal part \(0.332<0.5\)).

Answer:

\(43\)
