Question

I NEED HELP REALLY BADLY!!! THIS IS THE LAST PART OF MY COURSE!

The volume of a cylinder is 72 ft3. The volume of a cube is 36 ft3. What is the difference between the volume of a cone that fits exactly inside the cylinder and the volume of a pyramid that fits exactly inside the cube? Provide an explanation for your answer to receive full credit.

Answer 1

@windsylph @eric_d @RedNeckOutLaw @timo86m @1lorax2 @yomamabf @IdontGetit100 @ore_tee @Preetha @Ashleyisakitty @shyguybros @dsood15 @mathmate @dillonmtorres

Answer 2

Volume of cylinder = \(\pi r^2 h\)
Volume of cone = \(\frac{\pi r^2 h}{3}\)
Volume of square based pyramid = \(\large \frac{A_b h}{3}\)

Answer 3

is that the formula @mathmate ?

Answer 4

Finally there is
Volume of square based prism = \(A_b h\)
Yes, these are the formulas needed to do the calculations.

Answer 5

and how do I do that? @mathmate

Answer 6

Examine and compare the formulas to find a way to find the answers.

Answer 7

im horrible at geometry I have no idea how to do this @mathmate

Answer 8

Looking at the formula,
The cone is 1/3 the volume of the cylinder so 1/3(72)= ?
Then subtract that number from 72 to find the difference

Answer 9

Same with the other.
Looking at the formual, the pyramid is 1/3 the volume of the cube,
So 1/3(36)=? And that'll be the volume of the square pyramid.
Then find the differnce

Answer 10

I got 48 for the first one then I got 12 @nikato is that the answer?

Answer 11

First one is correct.
Remember to substact 12 from 36 for the second. You're suppose to find the difference between the two shapes

Answer 12

Then for the explanation. You can kinda use what I said above
And be sure to include the formulas mathmate provided

Answer 13

ok. so what would I like write for my answer, im not really good at summarizing everything together for my final answer @nikato

Answer 14

oh lol I sent that right after ok thank you @mathmate and @nikato

Answer 15

I think I pretty much stated it above^
It kinda also includes the explanation
