What is the approximate perimeter of a semicircle with a radius of 6 cm?

1 answer:

8 0

<span>So we want to know what is a perimeter of a semicircle whos radius is 6cm. So to find the perimeter we can use the formula for the circle and divide that in half. Because the semicircle is exactly one half of a circle. So the formula for the perimeter for a circle is O=2r*pi and for the semicircle is one half of that: O=r*pi=6*3.14=18.84cm.</span>

Step-by-step explanation:

I will be using money as an example.

It takes 4 quarters to make a dollar. (1/4 1/4 1/4 1/4 = 1)

By using this method we will know that it takes 24 quarters to make 6 dollars and the additional 1/4 is an extra quarter. Now that we have 25 quarters we will divide it by 3 because it takes 3/4 to make a bow.

6x4=24

24 + 1 = 25

25/3= 8.333333
