Can anyone advise on cooking time, method, size of pan, etc for cutting a cheesecake recipe in half? Original recipe calls for 9-10 inch pan.
 
You'll need to calculate the volume that the original recipe makes because it isn't half the diameter for your answer. There's a lot of maths in here but it's pretty basic maths, you just need to be able to calculate the volume of a cylinder.

So if your original recipe makes a cheesecake that is say 6cm high, then the volume calculation will be the surface area times the height, and the surface area is pi x radius squared. (the radius is half the diameter).

Putting that into google calculations, we get 2462cm cubed.

So now you just work that backwards after you have halved the volume, (halving all the ingredients means half the volume).

I'll round things up to 2463cm cubed.

So we want 1231.5cm cubed for our new volume of half the ingredients.

Divide this by pi, then by 6 and we'll have the radius squared which gives is 65.3.
All we need now is the square root of this and we'll have the size dish you need to keep the cheesecake at 6cm high.

This gives us the radius in cm. The radius is half of the diameter, so double the answer above and then convert it to inches.

You'll see in the top right hand corner of the next image that I have already double the radius.

So, if you halve the volume by halving all the ingredients and keep it at the same height (guessed at 6cm which is roughly 2.25 inches) you'll go from needing a 9inch tin to a 6inch diameter tin. If you change the height of the cheesecake, you'll obviously need a different sized thin again .
