Answer 2

Answer:

The answer is

$r=\sqrt{\frac{V}{\pi h} }$

step-by-step explanation:

A tube is a substance made up of two identical circles in parallel layers, their contents, and all the corresponding parallel lines having ends on the circular areas that are perpendicular to the includes the implementation the centers of both circles.

A three-dimensional solid's density is the volume of space it takes up. Cubic units are used to estimate area. Before calculating the volume, make sure that all of the measures are all in the same unit. The area of the bottom B twice the elevation h make up the intensity V of a tube with radius r.

Step 1: By dividing both sides with π

$\frac{V}{\pi } =\frac{\pi ^{2} h}{\pi }$

   $=r^{2} h$

Step 2: Subtract h from both sides

$\frac{V}{\pi h} =\frac{r^{2} h}{h}$

    $=r^{2}$

Step 3: Take ±√ both sides

±$\sqrt{\frac{V}{\pi h} } =r$

Step 4: Simply maintain the positive value because the radius, r, cannot be negative.

$r=\sqrt{\frac{V}{\pi h} }$
