Question

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?

44π ft3

24π ft3

52π ft3

176π ft3

Answer 1

help..? please...

Answer 2

I know that Vcylinder=pi*r2*h
and Vcone=1/3*pi*r2*h

Answer 3

but I dont know what h is for the cone...

Answer 4

is it 3..?

Answer 5

\[h_{\text{cone}}=13-10\]

Answer 6

thanks!

Answer 7

So Vcyl=pi*2^2*10 =125.7 and Vco=1/3*pi*2^2*3 =12.6
added together its 138.23
which is the same as 44*pi ft^3
right??

Answer 8

That's right.

Answer 9

yay! (:
