If I have a round cake which has a diameter of about 10" and I am serving cake to 10 people, how do I measure how big of an equal sized slice each person gets?
(please don't just give me the answer but also tell me how to figure it out)
Thanks

This is a MATH question. It is a ROUND cake so it is not as simple as 1" slices for 10 people cuz the DIAMETER is 10"

You want to cut 10 slices, equally spaced, right? So you need to find the circumference of the cake and divide that by 10 to figure out how far apart each slice should be at the rim of the cake. The formula is Circumference = pi * Diameter. You have the diameter given, and you know pi is 3.14etc., so the answer should be a piece of cake, right? Easy as pie!
Oh ho! I see I fell into your teacher's little trap - he wants the area of the slice, eh? Well the fellow above is right. If you want to get even fancier, you could multiply the area of the slice by the height of the slice to get the volume. (Make up a height if you so choose, but make sure you show your work!)

10 people for a 10 inch cake. It's easy math. Each person gets a one inch piece of cake.
10 divided by 10 is 1

Oh my god... Don't listen to them. What you do is you divide the diameter in half to get 5 for the radius, then you square it and multiply it by pi to get 25pi. pi(r^2)=area, and then you divide that by 10 people and that should give you the area of each piece. And height has nothing to do with it, because circles don't have a height, they have a diameter, and you can't find area from the diameter, you have to use the radius. If you want the percent, it's a different story.

How to do it: Eyeball it!
Cut the cake in half then eyeball out five slices from each size.
Do you think they are going to weigh their slice and complain?
Is this a party question or a math question, cause I only answered it as though you're REALLY serving a cake

you may desire to ask the guy making the cake what share it truly is meant to feed. distinctive sizes feed distinctive human beings (cake circumferences can fluctuate.) Then get adequate part or sheet tarts to make up for the version. as far as irritating approximately all of them being huge eaters and "ingesting adequate for 3 human beings" i'm valuable you're already offering a ship-load of nutrition. i might say one piece of cake consistent with man or woman. which will probable be a wierd sort and leave you with one extra a million/2 a sheet cake besides. some human beings won't consume cake, and if somebody starts off gorging out on diverse products it is only rude. And gross.

find the volume of the cake (i assume its a circular cake) volume = (pi)(r^2)h, where h is height
and divide that by 10 for 10 slices
or just find the area of the cake and divide that by 10

It depends on the type of cake. If you buy layer cake you can divide up the layers in a cake emergency if you have to.

10 inches divided by 10 people, if they all get the same size, it'll be one inch
10 div. by 10 =1
