answer:

1769.344983 or 1769.34 (depends on what you’re rounding to)

explanation:

- the equation for a cylinder‘s surface area is: (2 π r h)+(2 π r^2)

so 2 just means x2

π is just pi

r is your radius and for this equation your radius is 8 cm

and h is your height so for this equation your height is 27.2 cm

- so the equation filled in is:

(2 x π x 8 x 27.2) + (2 x π8^2) = 1769.344983 or 1769.34

(2 x π x 8 x 27.2) = 1367.221123

(2 x π8^2) = 402.1238597

1367.221123 + 402.1238597 = 1769.344983

hope this helps :)

Rewrite the expression as a product of two factors. 72t+8

Aneli [31]

Step-by-step explanation:

The above given expression "72t+8 " have to be factorized by the following methods.

Step 1 :

First we must check both numbers in order to obtain common factor for both ,for this equation "8" is the common factor for both .

Step 2:

After obtaining the common factor for the equation equation, we must now take the factor as common outside the bracket and form the equation as follows,

⇒ 8 * ( 9*t + 1 )

Here there are the two factors for the equation " 72 t+ 8 " that are 8 and 9t+1.

Step 3 (optional) :

Now check weather the factors are correct or not by multiplying factors with each other.

Multiplying ,

⇒ 8 * ( 9*t + 1 )

Gives -

⇒ 72 t+ 8

How many different three-digit numbers can be written using digits from the set 5, 6, 7, 8, 9 without any repeating digits?

suter [353]

Answer: 60 different numbers can be formed

Step-by-step explanation:

Note that we have 5 different digits, and we must select 3 of them. They should not be repeated

The order of selection is important in this case, because the number 532 is not the same as the number 235.

So we have a permutations problem, where we have a set of n elements and we want to choose r from them.

Then we define the permutacion as:

$nPr=\frac{n!}{(n-r)!}$

In this case note that n=5 because there are 5 elements in the set.

r = 3 because we combine the elements to form three-digit numbers

Then:

$5P2=\frac{5!}{(5-3)!}$

$5P2=\frac{5!}{2!}$

$5P2=\frac{5*4*3*2!}{2!}$

$5P2=5*4*3$

$5P2=60$

Help please hurry......

user100 [1]

All multiples of 15 between 0 and 300,inclusive

How?

$\\ \sf\longmapsto f(x)=15x$

$\\ \sf\longmapsto f(0)=15(0)=0$

$\\ \sf\longmapsto f(20)=15(20)=300$

Hence.

$\\ \sf\longmapsto 0\leqslant R_f\leqslant 300$
