Question

formula: d = c ÷ π use 3.14 for π. d = ? cm round to the nearest tenth.

Explanation:

Step1: Determine the circumference

Assume the circumference \(C = 12.56\) cm (since it's a common value for such problems when using \(\pi = 3.14\)).

Step2: Calculate the diameter

Using the formula \(d = C\div\pi\), substitute \(C = 12.56\) and \(\pi = 3.14\).

$$d=\frac{12.56}{3.14}=4.0$$

Answer:

\(4.0\) cm
