Question

question 5 of 5
a factory makes circular rugs with a radius of 3.5 feet. how much braid do they need to go all the way around the outside of the rug? use 3.14 for π.
a. 21.98 ft
b. 10.14 ft
c. 10.99 ft
d. 38.465 ft

Explanation:

Step1: Recall the formula for the circumference of a circle

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

Step2: Substitute the given values into the formula

Given \(r = 3.5\) feet and \(\pi=3.14\). Then \(C = 2\times3.14\times3.5\).
First, \(2\times3.5 = 7\).
Then \(C=7\times3.14\).

Step3: Calculate the product

\(7\times3.14 = 21.98\)

Answer:

A. \(21.98\) ft
