Question

List the order of the greatest volume to the least volume. When calculating use the pi key.
1.Cylinder with a height of 3 units and a radius of 4 units
2.Cone with a height of 2.74 units and a radius of 7 units.
3.Sphere with a radius of 3.2 units

Answer 1

Do you know how to do this?

Answer 2

No

Answer 3

OK lazor shall Ur friend teach u

Answer 4

Yus i really need help

Answer 5

Ok so for the first one

Answer 6

for the cilinder its hight times the radius

Answer 7

so 3 x 4?

Answer 8

Wait

Answer 9

its pi times radius to the power of 2 times the hight

Answer 10

V=πr2h

Answer 11

thats the equation?

Answer 12

yes

Answer 13

okie i will solve it

Answer 14

Plug what u know
in that equation

Answer 15

would it be 6.3?

Answer 16

no it would not

Answer 17

Post what u did

Answer 18

π·42·3≈150.79645

Answer 19

I dont think u Did 4 to the second power

Answer 20

So its 3.14 times 16 and then that times 3

Answer 21

Alright here's how you find out the volume of a cylinder first.

Our formula for this problem is
\[V=\pi r ^{2}h\]
All you have to do is plug in the numbers (''r'' represents radius, ''h'' for height)
\[\pi(4)^{2}(3)\]
You can use a calculator like desmos to figure this out, here's the link:

The answer would be
\[V=150.7964474\]

Answer 22

Our formula for the next problem is,
\[V=\frac{ 1 }{ 3 }\pi r ^{2}h\]
Just as before, plug in the choices
\[V=\frac{ 1 }{ 3 }\pi(7)^{2}(2.74)\]
You can use a calculator like desmos to figure this out, here's the link:

The answer would be
\[V=140.5967432\]
