Question

the radius of a circle is 3 miles. what is the circles circumference? round your answer to the nearest hundredth. miles

Explanation:

Step1: Recall the formula for circumference

The formula for the circumference \( C \) of a circle is \( C = 2\pi r \), where \( r \) is the radius.

Step2: Substitute the radius value

Given \( r = 3 \) miles, substitute into the formula: \( C = 2\pi\times3 = 6\pi \).

Step3: Calculate the numerical value

Using \( \pi \approx 3.14159 \), \( C \approx 6\times3.14159 = 18.84954 \).

Step4: Round to the nearest hundredth

Rounding \( 18.84954 \) to the nearest hundredth gives \( 18.85 \).

Answer:

18.85
