1. I would agree with 5 because a cone is 1/3 of its cylinder and 1/3 of 15 is 5

2. If the diameter is 6, then the radius is 6 ÷ 2 = 3, which also means the height is 3 × 3 = 9. To find the volume, we first need the area of its base circle, and we get this by doing π × radius^2 = π × 3^2 = 9π. Because they want us to use 3.14 as π, you do 9 × 3.14 = 28.26. We figured out the height earlier, so now all you do is 28.26 × 9 = 254.34

I hope this helps!

The table below shows four systems of equations:

fredd [130]

<span>System 1 and system 2, because the second equation in system 2 is obtained by adding the first equation in system 1 to two times the second equation in system 1

This is the correct answer because not only is it true but it also follows the property of solving systems of equations with adding the equations. To prove that it is true:

2nd equation in system #2 = 1st equation in system #1 + 2(2nd equation in system #1)

</span>10x − 7y = 18 == 4x − 5y = 2 + 2(<span>3x − y = 8)
10x - 7y = 18 == 4x - 5y = 2 + 6x - 2y = 16
10x = 7y = 18 == 10x - 7y = 18</span>
