Question

calculate the circumference.
formula:
c = πd
use 3.14 for π.
c = ? cm
round to the nearest tenth.

Explanation:

Step1: Convert the diameter unit

The diameter \(d = 12m=12\times100 = 1200cm\)

Step2: Substitute into the circumference formula

Given \(C=\pi d\), and \(\pi = 3.14\), \(d = 1200cm\)
\(C=3.14\times1200\)
\(C = 3768.0cm\)

Answer:

\(3768.0\)
