Question

Solve the formula V = pi r2h for r

Answer 1

Answer:

$V=\pi \times r^{2}\times h\\\\\Longrightarrow V=r^{2}\times \left( \pi \times h\right) \\\\\Longrightarrow r^{2}=\frac{V}{\pi \times h} \\\\\Longrightarrow r=\sqrt{\frac{V}{\pi \times h} }$

Answer 2

Answer:

root(V / hpi) = r

Step-by-step explanation:

i assume this is the volume of a cylinder and as such
V = pi * r^2 * h
divide both sides by hpi
V / hpi = r^2
root both sides
root(V / hpi) = r
