# The diameter of a semicircle is 6 miles. What is the semicircle's perimeter?

Accepted Solution

A:

Answer:[tex]15.42mi[/tex]Step-by-step explanation:Use the formula for a semicircle's perimeter.[tex]P=\frac{1}{2}\pi *d+d[/tex]Plug in 6 for d.[tex]P=\frac{1}{2}\pi*6+6[/tex]Let's use 3.14 for [tex]\pi[/tex], just to make it easier, but of course, if it states to round it to something else, just plug in that many values for [tex]\pi[/tex].[tex]P=\frac{1}{2}(3.14)*6+6 \\ \\ P=1.57*6+6 \\ \\ P=9.42+6 \\ \\ P=15.42[/tex]
