What is the volume of a 14 in diameter pipe that’s 2156 long?

Mathematics
1 answer:
storchak [24]3 years ago
4 0

Answer:


Step-by-step explanation:

given that diameter of the pipe = 14 inches

radius = 7 inches

Length =2156 inches

Pipe is in the form of a cylinder

Volume of cylinder = pi r^2 h

where r = radius and h = l = 2156

We have to substitute the values of r and h.

Let us take pi as 22/7

= 22/7 (7)(7)(2156)

Cancel out 7 and multiply the remaining 22 ,7 and 2156

=332024 cubic inches

If you have 30$ and you need to find 8%, and add to 30$ then find 15% of that, and what’s your total?
stira [4]

Answer:

Our total amount value is $4.86.

Step-by-step explanation:

The total amount given is $30.

Now  8 % of $30 = \frac{8}{100}  \times 30 = 2.4

or, 8% of $30  = $2.4

Now adding $30 and $2.4,

$ 30 + $2.4  = $32.4

Finding 15% of the total $32.4,

we get  \frac{15}{100} \times 32.4 = 4.86

or, 15% of $32.4   = $4.86

hence, our total amount value is $4.86.
