Answer 2

That's all it provides, sorry.

Answer 3

ok. hold on

Answer 4

Okay, thank you take your time.

Answer 5

21 i think for the pyramid and cube one

Answer 6

40.5 for the other I think. i could be very wrong.

Answer 7

hold on......ill b right back

Answer 8

Could you tell my how you're solving this? Also okay.

Answer 9

Answer 10

@.Sam.

Answer 11

can you help us?

Answer 12

the volume of the cone is one third(1/3) of the volume of the cylinder with the same height and radius.

some for the cube, the volume of the pyramid is one third(1/3) of the cube with the same base area and height.

Answer 13

@TheSmartOne

Answer 14

so the difference is

volume of cylinder - 1/3 volume of cylinder or you could just find 2/3 the volume of the cylinder...

same for the cube and pyramid

The formulas

Cylinder: \[V = \pi r^2 h\]

Cone with same radius and height

\[V = \frac{1}{3} \pi r^2h\]

hope it helps

Answer 15

wait so I find the volume of the cylinder and subtract is by 1/3?
sorry If I sound dumb I'm just trying to learn this.

Answer 16

well you are given the volume of the cylinder 81 ft^3

so find 1/3 of that... that is the volume of the cone...

then to find the difference its 81 - 1/3 of 81

does that make sense...?

Answer 17

and its the same for the cube and pyramid

Cube = 42 ft^3 pyramid will be 1/3 of 42

difference = 42 - 1/3 of 42

Answer 18

So for the Cube and Pyramid would it be 14?
and Cylinder and Cone would it be 27?

Answer 19

well for the cylinder/cone

Cylinder = 81 cone = 27

difference = 81 - 27

cube/pyramid

Cube = 42 pyramid = 14

difference = 42 - 14

Answer 20

Ah okay, I see now thank you so much!
