Question

what is the circumference of a circle with a radius of 11 feet? c = ? ft. do not round your answer. circumference formula c = 2πr use 3.14 for pi (π).

Explanation:

Step1: Identify the formula and values

We know the circumference formula \( C = 2\pi r \), where \( r = 11 \) ft and \( \pi = 3.14 \).

Step2: Substitute the values into the formula

Substitute \( r = 11 \) and \( \pi = 3.14 \) into \( C = 2\pi r \):
\( C = 2\times3.14\times11 \)

Step3: Calculate the result

First, calculate \( 2\times3.14 = 6.28 \), then \( 6.28\times11 = 69.08 \).

Answer:

\( 69.08 \)
