7 copper spheres with radii of 4
Anit [1.1K]

We will see that the cube must be 10.23 inches tall.

<h3>How tall is the cube?</h3>

The volume of the cube must be equal to the volume of the 4 spheres. Remember that the volume of a sphere of radius R is:

V = (4/3)*3.14*R^3

In this case, the radius is 4 inches, so we can write:

V = (4/3)*3.14*(4 in)^3 = 267.95 in^3

Then the volume of the 4 spheres is:

4*267.95 in^3 = 1,071.79 in^3

The volume of a cube of side length S is given by:

V = S^3

Then we must have:

S^3 = 1,071.79 in^3

S = ∛(1,071.79 in^3) = 10.23 in

We conclude that the cube is 10.23 inches tall.

Follow the instructions below.
sergeinik [125]

Answer:

1.    0.83 = 83%

2.    6.1% = 0.061

Step-by-step explanation:

The answer in number one is because when you're trying to find a percentage from a decimal, all you have to do is multiply your decimal by 100, this is because a percentage is always out of 100.

The answer in number two is exactly the opposite, all you have to do is divide by 100 if you are trying to find your decimal from a percentage.

Find the perimeter of ABCD and please explain how you found it.​
kkurt [141]

Answer:

157

Step-by-step explanation:

We can already tell that these two figures are congruent due to the angles (if you remember, the "top" and "bottom" angles of trapezoids form 180 degrees). Since we know that these are congruent, we know that GH = BC, and so on. We can then plug in the missing sides by looking at the figure that has the sides. Thus, giving us 157. Hope this wasn't too complicated!
