Question

How to find R of a cone?

Answer 1

If you are given the volume then
V=(1/3)hpir^2
h=height
r=radius
V=volume
solve for r

times 3 both sides
3V=hpir^2
dvivide both sides by hpi
$\frac{3V}{h \pi}=r^2$
sqrt both sides
$\sqrt{\frac{3V}{h \pi}} =r$

Answer 2

Multiply the volume by 3.
Multiply the height by π, which is a numeric constant that begins 3.14 and never terminates.
Divide the tripled volume by the product of the height and π.
Find the square root of the result from the 3rd step
