Question

find the circumference of this circle. use 3.14 for π. 3 cm circumference of a circle c=πd=2πr c=?cm round your answer to the nearest tenth.

Explanation:

Step1: Identify the diameter

The diameter \(d = 3\) cm.

Step2: Use the circumference formula \(C=\pi d\)

Substitute \(\pi = 3.14\) and \(d = 3\) into the formula: \(C=3.14\times3\).

Step3: Calculate the value

\(C = 9.42\).

Step4: Round to the nearest tenth

Since the second - decimal digit is \(2\) (less than \(5\)), \(9.42\approx9.4\).

Answer:

\(9.4\)
