Hey there,
Length (diameter)= 7 + 7
                            = 14 cm
Circumference = 2 x pi x r
                        = 2 x pi x 7
                        = 14 pi

Hope this helps ^_^

The cost for 15 cases of oranges is $75. What is the cost for 1 case? *
postnew [5]

Answer:Ok I This question can be solved using a system of equation, which requires translating the above word problem into something that can be algebraically

Let O=oranges and  Let G=Grapefruit

5O +8G=235

3O + 2G=85

To solve, you must isolate one of the variables and then work from there. To do that multiply both sides of the bottom or second equation by four and then subtract the bottom equation from the top.

Which would look like this

5O +8G=235

12O + 8G= 340

Then subtract the bottom from the top to get this

-7O=-105

Solving for O we divide both sides by -7, and end up with O=15

Plugging that value back into one of our original equations to solve for G we get this

3(15) + 2G= 85

45 +2G=85

2G=40

G=20

So 1 case of each altogether would equal 15+20, or $35.

<h3>Hope this helps have a awesome night/day❤️✨</h3>

What is 68,642 rounded to the nearest thousand?
Sergeeva-Olga [200]
68,642 rounded to the nearest thousand is 69,000.

It's because 68,642 is closer to 69,000 than to 68,000.

I hope it will help you and give a clue for rounding numbers in the future ;)

Got 3.2 from Second length is twice the third so we divide by 2 + 1 = 3

0.2 is from 1/5 = 0.2

3 is the third length

30 is second length and 15 is the first.
