Best ResponseYou've already chosen the best response.1volume = 1/3* pi *r^2*hdw:1352740094367:dw can you find h?

Best ResponseYou've already chosen the best response.1nop you used 50 in calculations.. as its not the height in this case.. can u see the diagram i drew?

Best ResponseYou've already chosen the best response.1yes but now i'm confused on what to do . can you type the equation for me and i will solve ?

Best ResponseYou've already chosen the best response.1well u first have to find the h.. h is the perpendicular height and its not given.. formula for cone is this. volume = 1/3* pi *r^2*h

Best ResponseYou've already chosen the best response.1i did : 1/3 * pi * 30^2 * 50

Best ResponseYou've already chosen the best response.1ok.. half is right .. the place where u had put 50 that is wrong. its not 50

Best ResponseYou've already chosen the best response.1ok.. would you able to see the picture if i draw here for u? because i posted pictures above but no respone about that from you.

Best ResponseYou've already chosen the best response.1ok find the value of "h" by Pythagoras theorem.

Best ResponseYou've already chosen the best response.1so 50^2 + 30 ^2 = c^2 ?

nubeer

Best ResponseYou've already chosen the best response.1not exactly.. the slanting height is "c" the base is "a" and height is "b"..

nubeer

Best ResponseYou've already chosen the best response.1so c^2=a^2+b^2 c=50, a= 30 , b= h can you find h now?

Best ResponseYou've already chosen the best response.1nooo.. 50^2  30^2 = h^2

nubeer

Best ResponseYou've already chosen the best response.1yes h^2 = 1600.. now take square root to find h.

nubeer

Best ResponseYou've already chosen the best response.1good.. this is your h now.. volume = 1/3* pi *r^2*h h=40, r =30 now plug it in formula.
