You multiply 5 by 1/5 to get 1. So with 2x, you multiply by 1/(2x) to get 1. That's about all you know, since we only know that x is positive.

Step-by-step explanation:

Hope it helps

$\frac{25}{10x-1}$

Step-by-step explanation:

The multiplicative inverse of "a" is " $\frac{1}{a}$ "

a × $\frac{1}{a}$ = 1

~~~~~~~~~~~

$\frac{1}{5}$ ( 2x - $\frac{1}{5}$ ) = $\frac{2}{5}$ x - $\frac{1}{25}$

1 ÷ ( $\frac{2}{5}$ x - $\frac{1}{25}$ ) = 1 ÷ ( $\frac{10x}{25}$ - $\frac{1}{25}$ ) = 1 ÷ ( $\frac{10x - 1}{25}$ ) = $\frac{25}{10x-1}$

The multiplicative inverse of the product is $\frac{25}{10x-1}$

area of base = $\pi r^2$

where 'r' is the radius

Step-by-step explanation:

Volume of the cylinder formula = $\pi r^2h$

volume of cylinder = area of base * height

The base of a cylinder is a circle. so we use the area of circle for the base of cylinder while finding volume

We know area of the circle is $\pi r^2$

So area of the base of cylinder is $\pi r^2$

To find volume of the cylinder , we multiply the base of the cylinder with height

To determine the base of the cylinder we need radius of the cylinder

area of base = $\pi r^2$

where 'r' is the radius
