Writing an expression to the total volume is nothing!! right?.
Just substitute the corresponding values to the variables, r & h
GoodFellow:
Give it a try
snowflake0531:
So practically you want to multiply the volume of the cylinder by 1 and a third, since the cone is a third of the volume .-.
So volume of cylinder \[V = \pi r^2(h)\]
snowflake0531:
What is the radius? what is the height

uhhhh wrote tha twrong, the height is different .-.
snowflake0531:
BUt either way, look at the cylinder first
xXQuintonXx:
the radius is 2
GoodFellow:
You are really trying, good job go ahead

Yes so \[3(2^2)(8)\] for the volume

Yes and now the cone \[\frac{1}{3} (\pi r^2 h)\]
snowflake0531:
What's the radius and height

radius would be 1.5 and height would be 8?
snowflake0531:
the cone bro

xXQuintonXx:
no questions asked xd
xXQuintonXx:
radius would be 2 and the height is 3

see! giving it a try leads you to the answer!
xXQuintonXx:
so its 3(2^2)(3)

yep
GoodFellow:
be careful! where is the denominator?
xXQuintonXx:
so the answer is 132?

uh the 3 and 1/3 crosses out .-.
xXQuintonXx:
mbmb xd
xXQuintonXx:
so its 2^2x3
snowflake0531:
yes lol
xXQuintonXx:
so its 108
