What is the volume, in cubic cm, of a cylinder with a height of 8cm and a base radius of 7cm, to the nearest tenths place?

FromTheMoon [43]

Answer:

Volume of the cylinder = $1230.88\,cm^3$

Step-by-step explanation:

Height(h) of the cylinder = $8 cm$

Radius(r) of the base= $7cm$

Volume of a cylinder is:

= $\pi \times r^2\times h$

As,

$\pi =\dfrac{22}{7} = 3.14$

Putting the values in the formula:

Volume is:

$=3.14\times(7\times7)\times8\\\\=3.14\times49\times8\\\\=3.14\times392\\\\=1230.88\,cm^3$

The volume of the cylinder is : $1230.88\,cm^3$

On a number line, point A has a coordinate of −6, and point B has a coordinate of 2. Which is the coordinate of point M, the mid

klasskru [66]

To solve this, we just need to find the distance between the points A and B in the number line, and then, divide that distance by 2.
Remember that the distance formula between tow point in the number line is:
$d=|x_{2}-x_{1}|$
From our point we can infer that $x_{1}=-6$ and $x_{2}=2$ , so lets replace the values:
$d=|x_{2}-x_{1}|$
$d=|2-(-6)|$
$d=|2+6|$
$d=8$

Now, to find the coordinate of the midpoint, we just need to divide that distance by 2:
$M= \frac{8}{2}$
$M=4$

We can conclude that the coordinate of the point M, the midpoint of AB, is 4

What is the height of a cylinder with a volume of 384 pi cubic inches and a radius of 8 inches? Round to the nearest tenth of an

Nataliya [291]

Answer: 1.9 inches

Step-by-step explanation:

- the equation to find the volume of a cylinder is V = π r^2 h

- so we can just change this equation around to H = V / π r^2

- so H = 384/ π 8^2 = 1.91 or 1.9

hope this helps :)
