i can help you with this give me one sec to draw my answer.
OpenStudy (anonymous):
thank you!
OpenStudy (anonymous):
so. the diameter= 1.87
now we have to consider the difference in size because of the walls which are .125
OpenStudy (anonymous):
i will draw a diagram to show
OpenStudy (anonymous):
ok

so we take the diameter and subtract the walls
0.125 x 2= .25
OpenStudy (anonymous):
1.87-.025=1.62
so 1.62 is our actual diameter
OpenStudy (anonymous):
now that we have that. we get our radius.
radius=1/2 the Diameter
OpenStudy (anonymous):
so our radius is .81

im sorry about before i did the problem and realized it required the formula for a cone not a cylinder because a funnel is in the shape of a cone so here is that formula:
1/3*pi*r^2*H
OpenStudy (anonymous):
then the answer would be
OpenStudy (anonymous):
where is the height in the problem it speaks of no height.
OpenStudy (anonymous):
it doesnt say
OpenStudy (anonymous):
ohhh. then i'm sorry i have just wasted you time wow. i feel bad. but anyways. ill try to find someone to help you one sec.
