The volume of the space not filled by the sphere is the difference between the volume of a cube with edge length 6 inches and the volume of a sphere with radius 3 inches.

The volume of a cube of edge length s is

... V = s³

When the edge length is 6 in, the volume is

... V = (6 in)³ = 216 in³

<h3><u>Sphere</u></h3>

The volume of a sphere with radius r is

... V = (4/3)π·r³

When the radius is 3 in, the volume is

... V = (4/3)π·(3 in)³ = 36π in³

<h3><u>Space</u></h3>

Then the volume of the space between the cube and the sphere is

... Vcube - Vsphere = 216 in³ - 36π in³ ≈ 102.9 in³ . . . . corresponding to choice C

What is it and why? having a good explanation would really help me. thx <3

Alexeev081 [22]

Answer:

B. (-4-2)

Step-by-step explanation:

since the numerator is one you can divide -8 by the denominator of each fraction. -8/2 = -4, -8/4 = -2

(-4-2)

You have to make sure you distribute the -8 to all parts inside the parenthesis for it to be right.

i hope this helps :)

jamie says the value of the expression 1.43 x (-20/39) is close to -0.75. Does jamie's estimate seem reasonable? explain. Jamie'

kherson [118]

Yes. J<span>amie's estimate seem reasonable.
This is because, when we expand the expression </span><span>1.43 x (-20/39) we get;

</span><span>1.43 x (-20/39) = -0.73333... (3 is repeating)

Her estimate was -0.75 while the actual answer is </span>-0.73333...
This is a good estimate since the difference is 0.016666.... which is negligible.
