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 \(C = 2\pi r\).

Step2: Substitute the values

Given \(r = 3\) m and \(\pi=3.14\), substitute into the formula: \(C=2\times3.14\times3\).

Step3: Calculate the result

First, \(2\times3 = 6\), then \(6\times3.14=18.84\).

Step4: Round to the nearest tenth

\(18.84\approx18.8\) (since the digit in the hundredth place is \(4\), which is less than \(5\)).

Answer:

\(18.8\)
