Answer:

Option C, 31.4\ cm

Step-by-step explanation:

<u>Step 1:  Determine the formula</u>

Formula → C = 2*\pi *r

<u>Step 2:  Determine the radius</u>

Radius = \frac{Diameter}{2}

Radius = \frac{10\ cm}{2}

Radius = 5\ cm

<u>Step 3:  Determine the circumference</u>

C = 2 * \pi * (5\ cm)

C = 10\ cm * \pi

C = 31.4\ cm

Answer:  Option C, 31.4\ cm

Help........ Again and thanks
Hunter-Best [27]

Answer:

x=3, y=1

Step-by-step explanation:

2x+y =7

3x-4y =5

Multiply the first equation by 4 so we can eliminate y

4(2x+y =7)

8x +4y =28

Add this to the second equation

8x +4y =28

3x-4y =5

----------------

11x = 33

Divide by 11

11x/11=33/11

x=3

Now we still need to find y

2x+y=7

2(3)+y =7

6+y=7

Subtract 6 from each side

6-6+y=7-6

y= 1

A number is 2/3 if another number. the sum of the numbers is 50. find the numbers
slava [35]

A number is 2/3 of another number.  Both added together equals 50.

One of these numbers consists of three parts, and the other consists of two of those three parts.  So, there are 5 equal parts in total.

Thus we need to divide 50 by 5.  50 divided by 5 equals <u>10</u>.

The first number, which has three parts, is 30.  The second number, which as two parts, is 20.

I hope this makes sense to you.  :D  Good luck in all your studies!
