Best ResponseYou've already chosen the best response.0volume of cone is: \[V={1\over3}\pi r^2 h\] we have V=12m^3 r = (6/2)=3m find h = ?

Best ResponseYou've already chosen the best response.3would the answer be 4? for the height???

Best ResponseYou've already chosen the best response.3because how i got it was right it was 4 and i did that by doing 1/3*3^2 and got 3 and the only one that would get me to 12 was 4 because 3*4= 12

Best ResponseYou've already chosen the best response.0you could use pythagoras' theorem to work out the height btw...cause it is a right angled triangle.

Best ResponseYou've already chosen the best response.0you could also substitute values into the formula and solve for h, which is the preferred method

Best ResponseYou've already chosen the best response.0are you still sure the question does not have a "pi" in there?

Best ResponseYou've already chosen the best response.0didn't @Skittles10412 write that 'for the 12 m^3 it should be 12pi m^3' at the top of the page?

Best ResponseYou've already chosen the best response.3yeah i had to retype it to make sure that people who were going to help me knew that it was 12pi m^3 not 12m^3

Best ResponseYou've already chosen the best response.3volume of cone = (1/3)(pi) x r^2 x h (pi) = 3.14159265359 6/2 = 3 12(pi) = (1/3)(pi) x 3^2 x h 12(pi) x 3 = (1/3 x 3/1) (pi) x 3^2 x h 36(pi) = (pi) x 3^2 x h 36(pi) = (pi) x 9 x h 36(pi)/(pi) = (pi)/(pi) x 9 x h 36 = 9 x h 36/9 = 9/9 x h 4 = h Answer = a) 4 m
