Question

find the circumference of this circle.
use 3.14 for π.
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

\(C = 3.14\times3=9.42\).

Step4: Round to the nearest tenth

Since \(9.42\) has \(2\) in the hundredth - place (\(2\lt5\)), the number rounded to the nearest tenth is \(9.4\).

Answer:

\(9.4\)
