What is the total volume of grains that can be stored in the silo?

Answer 1

*confused*
why does that picture's base look no circle..
or why does it have two heights? o-o
@Data_LG2 save me

Answer 2

I don't know ;w;w;w;w;w;w;

Answer 3

@mathstudent55 @freckles help? :3

Answer 4

o-o

Answer 5

I can't read that DX

Answer 6

I'm confused. @Data_LG2

Answer 7

lol sorry, I'll just try to write it, give me a sec.

Answer 8

o-o

Answer 9

@sleepyhead314 he left ;w;

Answer 10

I'm sorry but I really don't know how to do this problem :(

Answer 11

*eyes widen*
OHHHHHHH

Answer 12

Step by step help?I ish new to dis.

Answer 13

first, solve for the volume of cylinder
second, solve for the volume of cone
third, combine the two volumes :)

i think sleepyhead can do it from here :P

Answer 14

i really need to go :) see ya

Answer 15

thank you data! :)

Answer 16

Okay I do what now first?

Answer 17

here is the information you have been given:

diameter = 4
therefore radius = 2
then Height of cylinder = 8.5
and Height of cone = 13 - 8.5 = 4.5

then you have the equations
Volume of Cylinder = pi r^2 h
Volume of Cone = (1/3) pi r^2 h

Answer 18

So for the cylinder it is pi 2^2 8.5
And cone is pi 2^2 = 4.5?

Answer 19

cylinder is right :)
try the cone again

Answer 20

pi 1/3 2^2 4.5?

Answer 21

mhmm :)
right
then simplify both

Answer 22

Um. Cylinder 106.81 cone 18.84?

Answer 23

yes, then add them

Answer 24

125.65?

Answer 25

I got 125.66 but yeah :P

Answer 26

58π ft3
40π ft3
23π ft3
36π ft3
are my choices

Answer 27

oh right
they didn't want you to multiply the pi in
so 125.66 divivded by pi is?

Answer 28

12.74

Answer 29

40.01

Answer 30

mhmm 40

Answer 31

yay
i still have one more

Answer 32
