Solved: Given that V = 1/3pi r2 h , make h the subject.

20. Make $h$ the subject of the formula

Write down the given formula.
The formula for the volume of a cone is given as:
$V = \frac{1}{3}\pi r^2 h$
Isolate $h$ by multiplying both sides by 3.
$3V = \pi r^2 h$
Divide both sides by $\pi r^2$ to solve for $h$ .
$h = \frac{3V}{\pi r^2}$
The correct option is A.
$\boxed{\text{A. } h = \frac{3V}{\pi r^2}}$

Given that V = (1)/(3)pi r2 h , make h the subject.
