danjs · Answer

cylinder Volume

V = pi * radius^2 * height

put in V and radius, and solve

danjs · Answer

ml and cm^3 are the same here

anonymous · Answer

Its asking for the height...not volume

danjs · Answer

yes, 
Volume = pi * radius^2 * height

put in the given volume and radius, solve for the height

anonymous · Answer

So .....H=V/r2...right?

danjs · Answer

$$ h =\frac{ V }{ \pi*r^2 }$$

anonymous · Answer

Oh yeah thank you ^~^

danjs · Answer

=973.36 / (3.14*4.6*4.6) 
=973.36/66.44
=14.6

answer is not there,  if you leave the pi out it is 46, maybe they made a mistake

anonymous · Answer

Nope I got it ^~^

anonymous · Answer

It left the pi out so it was 46 XP
