1/3 pi r² 2r = 1........h = 2r
r³ = 1/(1/3 pi 2)
r = ³√0.4777
r = 0.7817
=> h = 2(0.7817)
=> h = 1.5634

given:
v(volume)=1
d(diameter)=h(height)
find: height "h"
solution:
formula for volume of cone: v=bh/3
1=((h/2)h)/3
1=(h*h/2)/3
1=(h*h)/6
h= squareroot of 6

V = (1/3).Ï.r².h
V = (1/3).Ï.(d/2)².h
V = (1/3).Ï.h³ / 4
V = (Ï/12).h³
h³ = 12V/Ï
h³ = 12 / Ï
h = (12/Ï)^(1/3)
h = 1.56
