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?
Answer

14π ft3

18π ft3

24π ft3

30π ft3

Answer 1

As shown below, please!

Answer 2

Split it into a cylinder and a cone.

Answer 3

You should be able to take it from there.

Answer 4

you would think... but im soo tired can you give me the equation i can def. do it from there

Answer 5

For the volume of a cylinder multiply the area of the circle \(\pi r^2\) times the height.

Answer 6

For the cone \(\dfrac{1}{3} \pi r^2 h\)

Answer 7

ok so 12.56 is the volume of the cylinder

Answer 8

But you have to wait until calculus to find out where the \(\dfrac{1}{3}\) comes from.

Answer 9

mmk and the volume of the cone would be 39.56 or 40 right and then i add the two?

Answer 10

Your choices all have\(\pi\) in them so you may want to not simplify your answer.

Answer 11

so i would add them up and then like devide by pi to simplify?

Answer 12

Not exactly, the area of the cylinder is \(\pi(2)^2(6)=24\pi\). You want to leave it as \(24\pi\)

Answer 13

ok got it so i just leave pi out of the equation since its in my answer

Answer 14

Yes you got it.

Answer 15

thank-you so much i know im tough to help but im not good at math and have been working since 6 this morning your help was greatly appreciated!!!!
