Question

find the circumference of the circle in terms of π. then use the approximation 3.14 for π and approximate the circumference.

a. find the circumference of the circle in terms of π
the exact circumference is □ yd

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.

Step2: Substitute the given radius

Given \(r = 5.1\) yards. So \(C=2\pi\times5.1 = 10.2\pi\) yards.

Answer:

\(10.2\pi\)
