Question

HELP ME PLEASE MEDAL AND FAN A company that manufactures storage bins for grains made a drawing of a silo. The silo has a conical base, as shown below.
What is the total volume of grains that can be stored in the silo? (5 points)


Question 5 options:

1) 58π ft3

2) 40π ft3

3) 23π ft3

4) 36π ft3

Answer 1

Theres the pic of the diagram

Answer 2

@sidsiddhartha

Answer 3

@confluxepic @texaschic101

Answer 4

so anyone?

Answer 5

What do you think it is. @Cntrl_Alt_Defeated

Answer 6

i think its D

Answer 7

but im probably wrong

Answer 8

awww the picture is still loading :(

Answer 9

so first tell me what is volume of a cone and of a cylinder

Answer 10

v=3.14r2h

Answer 11

/3

Answer 12

i believe?

Answer 13

yeah
\[v_{cyl}=\pi r^2h\\v_{cone}=\frac{ \pi r^2h }{ 3 }\]

Answer 14

Yes. @Cntrl_Alt_Defeated
I believe you are correct but let @sidsiddhartha explain it to make sure.

Answer 15

now from the picture can u tell me what is the height of the cone?

Answer 16

\[h_{cone}=13-8.5\]
right?

Answer 17

yes
4.5

Answer 18

so
\[v_{cyn}=\pi.2^2.13\\and \\v_{cone}=\frac{ \pi.2^2 .(4.5)}{ 3 }\]
right?

Answer 19

yep

Answer 20

sorry for \[v_{cyl}=\pi 2^2.(8.5)\]

Answer 21

because h(cylinder)=8.5

Answer 22

now just add them and see what u get :)

Answer 23

i got 106.81

Answer 24

no \[V_{cyn}+V_{cone}=\pi. 2^2.*8.5+\frac{ \pi 2^2.4.5 }{ 3 }=4 \pi(8.5+1.5)=40 \pi\]

Answer 25

oh oops i only did the cylinder

Answer 26

:)

Answer 27

thnx

Answer 28

yw!!
