Question

1. a paper - towel tube is about 4 cm in diameter. the circumference of a paper - towel tube is about how many centimeters? (use 3.14 for π.)

Explanation:

Step1: Recall the formula for circumference

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

Step2: Substitute the given values

Given that \(d = 4\) cm and \(\pi=3.14\). Substitute these values into the formula: \(C=3.14\times4\).

Step3: Calculate the result

\(3.14\times4 = 12.56\)

Answer:

\(12.56\)
