is that a cone on top of the cylinder?

OpenStudy (acxbox22):

if it is then you need to find the volume of the cone and the cylinder then add the 2 volumes to get youtr total volume

OpenStudy (anonymous):

ok

OpenStudy (acxbox22):

cone: \[V=\frac{ 1 }{ 3 }\pi r^2 h\] cylinder: \[\pi \approx 3.14\] height for cone is 15ft height for cylinder is 60ft radius is 10ft substitute the values into the formula

OpenStudy (agent0smith):

Cylinder volume: \[\large V = \pi r^2 h\]r=10 and h = 60. plug them in Cone volume \[\large V=\frac{ 1 }{ 3 }\pi r^2 h\]r= 10 and h=15. plug them in Lastly, add those two volumes together

18,840+ 1,570=20,410 @agent0smith

OpenStudy (anonymous):

is that right? i dont think it is

OpenStudy (agent0smith):

\[\large \pi*10^2*60 + \frac{ 1 }{ 3 }\pi *10^2*15\]use a calculator

i got them all right nvm
