Question

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

Explanation:

Step1: Substitute values into formula

Given \( C = 40\) cm and \( \pi=3.14\), substitute into \( d = C\div\pi\).
\(d = 40\div3.14\)

Step2: Calculate the division

\(40\div3.14\approx12.7\) (rounded to the nearest tenth)

Answer:

\(12.7\) cm
