To find a volume of a cylinder you use the formula pi r^2 h. You have h=18.75 but are missing r. To find r you make a right triangle. Then use A^2 +b^2=c^2; where a =18.75 b=diameter, and c=21.25. After solving you get the diameter equals 10. Now cut that in half to get the radius =5. Now you can use the volume equation. Plugging in you have pi*(5)^2*18.75. This will give you 1472.62m^3

zysi [14]

Answer:

$\frac{f}{g} =\frac{3x+1}{5x-1}$

$x\neq \frac{1}{5}$

Step-by-step explanation:

we are given

$f(x)=3x+1$

$g(x)=5x-1$

we have to find f/g

we can write as

$\frac{f}{g} =\frac{f(x)}{g(x)}$

now, we can plug values

and we get

$\frac{f(x)}{g(x)} =\frac{3x+1}{5x-1}$

so,

$\frac{f}{g} =\frac{3x+1}{5x-1}$

we know that denominator can not be zero

so,

$5x-1\neq 0$

now, we can solve for x

$5x-1+1\neq 0+1$

$5x\neq 1$

Divide both sides by 5

and we get

$x\neq \frac{1}{5}$
