Question

find the circumference of this circle. use 3.14 for π. circumference of a circle ( c = pi d = 2pi r ) ( c = square? m ) round your answer to the nearest tenth.

Explanation:

Step1: Identify the formula

The formula for the circumference of a circle is \(C = \pi d\), where \(d\) is the diameter.

Step2: Substitute the values

Given \(d = 12\) m and \(\pi=3.14\), substitute into the formula: \(C = 3.14\times12\).

Step3: Calculate the result

\(3.14\times12 = 37.68\).

Step4: Round to the nearest tenth

\(37.68\approx37.7\) (since the digit in the hundredth place is \(8\gt5\), we round up the digit in the tenth place).

Answer:

\(37.7\) m
