Question

A 6 inch personal pizza has 600 calories, with 240 of those from fat. A 16 inch pizza is cut into 8 slices. Estimate the number of calories in one slice of a 16 inch pizza.

Answer 1

I think you may need to scale this by area.
\[\frac{ 6"area }{ 16"area }=\frac{ 6"calories }{ 16"calories }\]
So for calories you'd have \[\frac{ \pi(6^2) }{ \pi(16^2) }=\frac{ 600 }{ x }\]
or\[\frac{ 36 }{ 256 }=\frac{ 600 }{ x }\]
x is the calories in a whole 16" pizza, so divide by 8 to get the calories in one slice.


Then do the same for fat calories, except change 600 to 240

Answer 2

thank you so much! i understand it now!
