Find the perimeter of the figure to the nearest hundredth.

Kryger [21]

Hello!

Your answer should be 26.85.

We can use the formula of pi d or 2 pi r for the circumference.

You would get 5 pi.

But since its not a full circle you would divide it in half and get 2.5 pi.

2.5 pi is equal to 7.85.

Now we can use the equation 7.85 + 7 + 7 + 5

That would equal our answer... 26.85!

Hope this helps!

Answer:

1/2 = 3/6

1/3 = 4/12

1/5 = 2/10

1/4 = 5/20

Step-by-step explanation:

To make equivalent fractions, you need multiply by 1. A number divided by itself is 1.

1/1 * x/x = x/x = 1

1/2 = 3/6

$\frac{1}{2} * \frac{3}{3} = \frac{3}{6}$

1/3 = 4/12

$\frac{1}{3} * \frac{4}{4} = \frac{4}{12}$

1/5 = 2/10

$\frac{1}{5} * \frac{2}{2} = \frac{2}{10}$

1/4 = 5/20

$\frac{1}{4}*\frac{5}{5}=\frac{5}{20}$

Hope this helps :)

Have a great day!
