How would you find H??

OpenStudy (ikram002p):

H ? do you mean height ? it says find the volume :o

OpenStudy (ikram002p):

u have H already on the graph

OpenStudy (anonymous):

Wait what??

OpenStudy (cwrw238):

volume = 4 8 area of the triangle

OpenStudy (cwrw238):

* 4 * area triangle

OpenStudy (anonymous):

Oh... I see!!

OpenStudy (anonymous):

Oh i thought that was the width! Thank you, stupid mistake....

OpenStudy (anonymous):

that's not height of triangle to find the area of triangle though.

OpenStudy (ikram002p):

Hence volume= area of triangle * height area of triangle = base of triangle * height of triangle you can find heigh of triangle from phyagorouse since u have the side and the base

OpenStudy (ikram002p):

yeah i note that hehe

OpenStudy (anonymous):

Yeah thats what I was trying to figure out

OpenStudy (anonymous):

hehe xD

OpenStudy (anonymous):

a^2 + b^2 = c^2 (4.5)^2 + b^2 = 9^2 \[b= 4.5\sqrt{3} = 7.794\]

OpenStudy (anonymous):

Anyone here good with circles and finding the shaded areas and stuff like that, i get everything but that...\

OpenStudy (anonymous):

or you can use the relationship betwen 30 60 90 triangle to figure it out. so height = 7.794

OpenStudy (ikram002p):

sure @claritamontano just post ur questions :D

OpenStudy (anonymous):

Yeah! @ikram002p are you a super genius??

OpenStudy (ikram002p):

haha nope :P not genuis at all
