If we solve for radius
V=1/3pir^2h
divide both sides by pih
V/(pih)=1/3r^2
times 3 both sides
3V/(pih)=r^2
sqrt both sides
sqrt(3v/(pih))=r

so if h=10
v=300
then
sqrt(3*300/(pi*10))=r
sqrt(900/10pi)=r
sqrt(90/pi)=r
use calculator
5.35=r

If f(x) varies directly with x, and f(x) = 12 when x = 8, write the direct linear variation equation.
Feliz [49]
<span>f(x) varies directly with x.
f(x) = kx (k is the constant of proportionality)
if x = 8,
12 = 8 k
k = 12/8
k = 3/2
So the equation would be: 
f(x) = (3/2)x
