Question

a circle has a radius of 11 m. what is its circumference? use 3.14 for π, and do not round your answer. be sure to include the correct unit in your answer.

Explanation:

Step1: Recall the formula for circumference of a circle

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

Step2: Substitute the given values

We are given that the radius \( r = 11 \) m and \( \pi = 3.14 \). Substituting these values into the formula, we get \( C = 2\times3.14\times11 \).

Step3: Perform the multiplication

First, calculate \( 2\times3.14 = 6.28 \). Then, multiply this result by 11: \( 6.28\times11 = 69.08 \).

Answer:

\( 69.08 \) meters
