OpenStudy (anonymous):

OpenStudy (anonymous):

cone = (1/3) b h = 1/3 pi r ^2 h

OpenStudy (anonymous):

Answer i got doesn't match any of the choices.

OpenStudy (anonymous):

but the ans is correct!? :P u wud get 1092.8 or something which rounded approx 1093 m3

OpenStudy (anonymous):

you have 1/3 * b * h = 1/3 * pi r^2 * 29

OpenStudy (anonymous):

i got 41770

OpenStudy (anonymous):

what is the radius?

OpenStudy (anonymous):

i used 13 as the radius...which isn't right is it

OpenStudy (anonymous):

nope, 12 is the diameter and the radius is half that

OpenStudy (anonymous):

6

OpenStudy (anonymous):

so that's 1/3 * 3.14 * 6^2 * 29 =

OpenStudy (anonymous):

1092.7

OpenStudy (anonymous):

which would be B

OpenStudy (anonymous):

that's it, the error is that we used 3.14 and not the whole pi buts its close enough

OpenStudy (phi):

to get a better match you should use the pi key on your calculator or use pi=3.14159
