OpenStudy (sonyalee77):

find the volume using pi = 3.14

OpenStudy (sonyalee77):

@ajprincess

@ml1042903

OpenStudy (ajprincess):

the formula to find the volume of a cone is 1/3pi r^2h. does that help?

OpenStudy (sonyalee77):

no

@ganeshie8

OpenStudy (sonyalee77):

@nubeer

OpenStudy (nubeer):

hmm did u tried the formula @ajprincess told u @Sonyalee77 ?

OpenStudy (sonyalee77):

thats the problem i don't now how to use it

OpenStudy (nubeer):

well do u know what is "r" ?

OpenStudy (sonyalee77):

radius

OpenStudy (nubeer):

yes the value of it

OpenStudy (nubeer):

from the diagram?

OpenStudy (sonyalee77):

i dont knnow

OpenStudy (nubeer):

see the base line.. its the diameter.. which is 16.. so radius = diameter /2 now tell me what would be the radius.

OpenStudy (sonyalee77):

8

OpenStudy (nubeer):

good and u can see the height of cone . h= 13 volume = (1/3)* pi * h* r^2

OpenStudy (nubeer):

now plug in the values in formula

OpenStudy (anonymous):

First you multiply 3.14 by 16^2= u figure it out. B*h (base*height). 3.14*16^2 answer times 13. Tada, I hope! Stay cool B)!

OpenStudy (sonyalee77):

871

OpenStudy (sonyalee77):

so that's the answer

OpenStudy (sonyalee77):

?

OpenStudy (nubeer):

yes
