Question

which of the following is closest to the circumference of a circle with a radius of 18 feet? a. 113.04 feet b. 226.08 feet c. 1017.36 feet d. 2034.72 feet

Explanation:

Step1: Recall the formula for circumference

The formula for the circumference of a circle is $C = 2\pi r$, where $r$ is the radius and $\pi\approx3.14$.

Step2: Substitute the given radius

Given $r = 18$ feet, then $C=2\times3.14\times18$.
First, $2\times18 = 36$, then $36\times3.14= 113.04$ feet.

Answer:

A. 113.04 feet
