if a sphere ,cylinder & a cone have same radius & height , what is the ratio?

Answer 1

Ratio of what?
Surface area?
Volume?

I will go with volume.

assume radius of sphere is = 1

sphere = 4/3pi
cylinder = 2pi
cone = 2/3 pi

eat the pi's (get rid of them) and multiply what's left by 1.5

Sphere:Cylinder:Cone = 2:3:1

I hope that helps

Answer 2

Cylinder Cone Sphere

Answer 3

I'm assuming it's the ratio of the volume.

For the height of the sphere to be equal to the height of the cone and cylinder then, height h must be equal to 2r.

Volume of Sphere: 4/3 π r^3

Volume of Cylinder: π r² h
Volume of Cylinder: π r² 2r
Volume of Cylinder: 2π r² r
Volume of Cylinder: 2π r^3

Volume of Core: 1/3 π r² h
Volume of Core: 1/3 π r² 2r
Volume of Core: 2/3 π r² r
Volume of Core: 2/3 π r^3

Ratios of: Sphere : Cylinder : Cone
Ratios: 4/3 π r^3 : 2π r^3 : 2/3 π r^3 (÷ π r^3)
Ratios: 4/3 : 2 : 2/3 Converting to thirds.
Ratios: 4/3 : 6/3 : 2/3 (x 3).
Ratios: 4 : 6 : 2
Ratios: 2 : 3 : 1

Answer 4

The Question is very simple!!!!


sphere = 4/3pi
cylinder = 2pi
cone = 2/3 pi

eat the pi's (get rid of them) and multiply what's left by 1.5

Sphere:Cylinder:Cone = 2:3:1

Answer 5

(4/3)pi(1)3:pi(1)^2(1):(1/3)pi(1)^2(1)
so the ratio of sphere:cykinder:cone
=4:3:1 will be the ratio of the volume

Answer 6

you can find the ratio of the volumes or the areas.
