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

koban [17]

Answer:

$15.42mi$

Step-by-step explanation:

Use the formula for a semicircle's perimeter.

$P=\frac{1}{2}\pi *d+d$

Plug in 6 for d.

$P=\frac{1}{2}\pi*6+6$

Let's use 3.14 for $\pi$ , just to make it easier, but of course, if it states to round it to something else, just plug in that many values for $\pi$ .

$P=\frac{1}{2}(3.14)*6+6 \\ \\ P=1.57*6+6 \\ \\ P=9.42+6 \\ \\ P=15.42$

Answer:

2 : 1

Explanation:

$\sf area \ of \ sector: \dfrac{\theta}{360} \pi r^2$

1st sector:

$\sf \rightarrow area: \dfrac{80}{360} \pi (8)^2 = 44.68 \ cm^2$

2nd sector:

$\sf \rightarrow area: \dfrac{160}{360} \pi (4)^2 = 22.34 \ cm^2$

Ratio of 1st sector to 2nd sector:

44.68 : 22.34

2 : 1
