The diameter of a sphere is 21.6 cm. What is the sphere's volume? Round to the nearest tenth, if necessary.

NeX [460]

By definition, the volume of a sphere is:
$V = \frac{4}{3} (\pi) (r ^ 3)
$
Where,
r: sphere radio
Substituting values we have:
$V = \frac{4}{3}(3.14)(( \frac{21.6}{2} ) ^ 3)
$
$V = 5273.99424
$ Rounding the result to the nearest tenth:
$V = 5274.0 cm ^ 3
$ Answer:
the sphere's volume is:
$V = 5274.0 cm ^ 3$

How many 3/4 foot lengths of pipe can be cut from a 7 and 1/2 foot pipe?

stiks02 [169]

Answer:

The number of pipes to be cut from total length of pipe is 10 pipes

Step-by-step explanation:

Given as :

Total length of pipe = l = 7 $\frac{1}{2}$ foot

i.e ' = $\frac{15}{2}$ foot

The length of pipe to be cut = l' = $\dfrac{3}{4}$ foot

Let The number of pipes to be cut = n pipes

<u>According to question</u>

The number of pipes to be cut = $\dfrac{\textrm Total length of pipe}{Length of pipe to be cut}$

i.e n = $\dfrac{l}{l'}$

Or, n = $\frac{\frac{15}{2}}{\frac{3}{4}}$

Or, n = $\frac{15\times 4}{3\times 2}$

or, n = 5 × 2

∴ n = 10 pipes

So, The number of pipes to be cut = n = 10 pipes

Hence, The number of pipes to be cut from total length of pipe is 10 pipes Answer
