Question

the radius of a circle is 47 feet. what is the circles circumference? round your answer to the nearest hundredth. feet

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 given radius

Given \( r = 47 \) feet, substitute into the formula: \( C = 2\times\pi\times47 \).

Step3: Calculate the value

First, calculate \( 2\times47 = 94 \), so \( C = 94\pi \). Using \( \pi \approx 3.14159 \), we get \( C \approx 94\times3.14159 \approx 295.30946 \).

Step4: Round to the nearest hundredth

Rounding \( 295.30946 \) to the nearest hundredth gives \( 295.31 \).

Answer:

295.31
