Answer:
243π inches
Step-by-step explanation:
The volume of a cylinder is πr^2 * h
r = 9
h = 3
81π * 3 = 243π
It is 60 dollars because you work backwards so you multiply 7.50 by 4 and 2.
Alright, lets get started.
Suppose the smaller integer = n
So, larger integer will be = n+2
3 times of larger integer will be = 
smaller integer is added into this , so

The result is 2 less than 5 times of smaller integer, so

Both are equal so,


Rafael makde the mistake that he didn't put the larger integer into parenthesis like (n+2) , so three times will be 3 n + 6 as he got 3n + 2
So, the correct equation is

Solving the equation


So, saller integer is 8 and larger integer is 
So, both integers are 8 and 10. : Answer
Hope it will help :)
We don't know what the dimensions are, but any numbers that have a sum of 120 will work. Let's use 3, 4, and 10.
3 x 4 = 12 10 x 12 = 120
But if you double each dimension:
6 x 8 = 48 48 x 20 = 960 To find how much the sums changed:
960 / 120 = 8
The new volume is 8 times what it originally was! 960 in.
So if you want to solve for c, the best thing to do is isolate the variable. So I personally don't enjoy dealing with fractions that much until the very end, so I am going to multiple the entire equation by

to eliminate the fraction. So now the equation is

. In order to isolate the c variable, subtract both sides by

, which makes it

. Now divide both sides by g,

. So that's what c equals in terms of f, d and g.
