A cylinder is placed within a cube. The diameter of the cylinder is equal to the length of each side of the cube. What is the vo

pochemuha

The volume of a shape is the amount of space in it.

<em>The volume outside the cylinder, but inside the cube is 214.6 cubic inches</em>

The given parameter is:

$l = 10$ ---- length of the cube

So, the volume of the cube is:

$V_1 = l^3$

$V_1 = 10^3$

$V_1 = 1000$

The volume of the cylinder is:

$V_2 = \pi r^2h$

The diameter (d) of the cylinder equals the length of the cube.

This means that:

$d = l$

$d = 10$

Divide by 2 to calculate the radius of the cylinder

$r = \frac{10}{2}$

$r = 5$

Also, the height of the cube is::

$h =l$

$h =10$

So, we have:

$V_2 = \pi r^2h$

$V_2 = \pi \times 5^2 \times 10$

$V_2 = \pi \times 25 \times 10$

$V_2 = \pi \times 250$

$V_2 = 785.4$

So, the volume (V) outside the cylinder is:

$V = V_1 - V_2$

$V = 1000 - 785.4$

$V = 214.6$

Hence, the volume outside the cylinder is 214.6 cubic inches

A number is 6.14 what way represent the value of the 4 in 6.14

Lady_Fox [76]

Answer:

Step-by-step explanation:

the value of the 4 in 6.14 is 0.04.

this is because the 4, or in this case 0.04

is in the hundredths place. So it is

suppose to have 0, where the 6 goes (also

the ones or units) The decimal point, another 0

where the 1 goes, ( the tenths) and finally back

to the 4. (Like I said, it’s the hundredths place)

so there you have it. Your answer will be 0.04

Janet wants to plant a square flower garden in her yard. She has enough topsoil to cover an area of 30 square feet. How long can

gregori [183]

It can be at least 5.4 feet long since the area of a square is A=s^2. 5.4 times 5.4 is 30
