Could you help me with this?
Which would help to calculate the volume of the composite figure shown?
first could you tell me what shape that is?
it looks like a prism...
no idea what kind though
Anyone know what formula i would use to solve this?
that seems like the combination of prism and a semicirclular figure with uniform height ... do you have the dimensions ?
^that's needed. rough idea would be base area x height..so dimensions would be fantastic
nope, it doesnt come this the dimensions, the question is asking what formula to use and i dont know which formula that is... here are the answers...
base times side one-half times pi times diameter times height one-third times length times width times height pi times radius times slant height
i am sorry dear moderator. i had no idea i unconsciously stated an answer. please don't ban me again
lets see... semicicular region, area = 1/2 pi radius ^2 |dw:1372858384560:dw|
you did state the answer ? i missed it!
let's keep it that way then
hartnn, i dont really understand what you drew?
The base is a rectangle if thats what you were asking
i drew the base region, sorry for my bad drawing :P
oh okay :p so you think the formula is area = 1/2 pi radius ^2 ?
thats just for semicircular part... but we need to add the area of rectangle too (1/2 pi r^2) + (2r)*(other side) but you choices do not contain the + (addition) part ..:\
oh :/ just from the answers which one would you think it is?
let me guess, the answer must contain 'pi' due to circular region, so 2nd and 4th alternative but they only differ by the word 'slant' ! (because half of diameter = radius)
are you sure, choices are correct ? because a volume should contain '3' dimension of length!
I would say its B and yes these are the correct answers
because once you have done the half circle there isnt anything that has to be done with a slant
see, your choices a,b,d have only 2 dimensions of length, they all are AREAS!
only choice 'c' is volume but it doen't contain pi :\
if the 1st choice is base 'area' times side, then it can be the answer
Yeah i would actually say its C and yes it does the answer on my screen is 1/3TTr^2h
I guess i did mess up the answers sorry :/
ohh..but 'c' didn't describe 1/3 pi r^2 h... anyways, no problem :)
