Question

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

Explanation:

Step1: Substitute the values into the formula

Given \( C = 22\) cm and \(\pi=3.14\), use the formula \(d = C\div\pi\). So, \(d = 22\div3.14\).

Step2: Calculate the division

\(22\div3.14\approx7.0\) (rounded to the nearest tenth).

Answer:

\(7.0\) cm
