Question

the diameter of a circle is 10 ft. find the circumference to the nearest tenth.

Explanation:

Step1: Recall the formula for circumference

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

Step2: Substitute the value of diameter

Given \(d = 10\) ft. Substitute into the formula: \(C=\pi\times10\).

Step3: Calculate the value

Using \(\pi\approx3.14159\), then \(C = 10\times3.14159=31.4159\) ft.

Step4: Round to the nearest tenth

Rounding \(31.4159\) to the nearest tenth (one - decimal place). The digit in the hundredth place is \(1\) (\(<5\)), so we keep the tenths place digit as it is.

Answer:

\(31.4\) ft
