Question

the diameter of a circle is 19 m. 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 \(d = 19\) m. Substitute into the formula: \(C=\pi\times19\).

Step3: Calculate the value

Using \(\pi\approx3.14159\), \(C = 19\times3.14159=59.69021\) m.

Step4: Round to the nearest tenth

Rounding \(59.69021\) to the nearest tenth. The digit in the hundredth place is \(9\), so we round up the digit in the tenth place. \(59.69021\approx59.7\) m.

Answer:

\(59.7\) m
