Question

1. find the circumference. round to the nearest hundredth. 25 m

Explanation:

Step1: Recall the formula for circumference

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

Step2: Substitute the given diameter

Given \(d = 25\) m. So \(C=\pi\times25\).

Step3: Calculate the value

Using \(\pi\approx3.14159\), \(C = 3.14159\times25=78.53975\).

Step4: Round to the nearest hundredth

Rounding \(78.53975\) to the nearest hundredth (two decimal places), we look at the third decimal digit. Since \(9>5\), we round up. So \(78.53975\approx78.54\).

Answer:

\(78.54\) m
