OpenStudy (volleyballlover55):

??

OpenStudy (squidnnneyyy):

ok, volume is LxWxH

OpenStudy (volleyballlover55):

ok...

OpenStudy (smartnerd1111):

um volume is difrent for diffrent shapes so squid is incorrect,he is thinking of a quadilateralo like a square or reectangle

OpenStudy (smartnerd1111):

Vcylinder=hpir^2 Vcone=1/3hpir^2 vcone h=6 r=3/2=1.5 v=1/3*pi*6*1.5^2 V=2pi*2.25 V=4.5pi vcylinder r=3/2=1.5 h=5 v=5*pi*1.5^2 v=5pi*2.25 v=11.25pi minus A-B=4.5pi-11.25pi=6.75pi pi=3.14

:P @smartnerd1111 got it ^^

OpenStudy (smartnerd1111):

yes

OpenStudy (volleyballlover55):

wait so then whats the answer?

OpenStudy (smartnerd1111):

OpenStudy (volleyballlover55):

ok next!

Use Pythagorean Theorem.... \(\Huge{a^{2}+b^{2}=c^{2}}\)

563blackghost (563blackghost):

Plug in your values... \(\Huge{6^{2}+8^{2}=c^{2}}\)

OpenStudy (smartnerd1111):

it is 8 centemiters because the square under the triangl is the sequal to the other square on the x

563blackghost (563blackghost):

That would be incorrect.... \(\huge{6^{2}=8^{2}=c^{2} \rightarrow 36+64=c^{2}}\) \(\huge\color{red}{100=c^{2} \rightarrow \sqrt{100}=c}\) In which 10 times 10 would equal 100 so it would be 10....

563blackghost (563blackghost):

Ooops meant... + not = for the first part of the equation....

OpenStudy (smartnerd1111):

oh
