Question

A cylinder and a cone have the same diameter: 8 inches. The height of the cylinder is 9 inches. The height of the cone is 18 inches.

Use π = 3.14.

What is the relationship between the volume of this cylinder and this cone? Explain your answer by determining the volume of each and comparing them. Show all your work.

Answer 1

do you know how to find the volume of the cylinder and cone?

Answer 2

maybe... @sleepyjess

Answer 3

do you know the formulas?

Answer 4

\[v = 3.14 r^2 h\]

Answer 5

Okay, now look up the cone.

Answer 6

it says its a 3-d shape with a flat bottom...

Answer 7

@sleepyjess

Answer 8

ok you have the formula for the volume of the cylinder, can you find the volume?

Answer 9

thats what i need help with @sleepyjess

Answer 10

\(v=3.14*r^2*h\) r=diameter/2

Answer 11

so about 452

Answer 12

yes

Answer 13

for a cone \(V=3.14*r^2*\dfrac{h}{3}\)

Answer 14

just do the same thing with the cone as you did for the cylinder

Answer 15

so 1206

Answer 16

can you show me what you did to get to that?

Answer 17

i plugged the 8 and 18 into that formula you gave me

Answer 18

remember r=diameter/2

Answer 19

radius is half of diameter?

Answer 20

So about 302

Answer 21

thanks.. gave you the medal you deserved

Answer 22

it would actually be 301 since the real value is 301.44.

Answer 23

tk can you help me again?
