Question 1184649


 

 
 
The {{{6}}} inches and {{{14}}} inches are (presumably!) the {{{diameters}}} of the two pizzas.

{{{A[6]= pi*r^2}}}
{{{r=3}}}
{{{A[6]= pi*37^2}}}
{{{A[6]= 9pi}}} 


{{{A[14]= pi*r^2}}}
{{{r=7}}}
{{{A[14] = pi*7^2}}}
{{{A[14] = 49pi}}}


{{{6}}} inch personal pizza has{{{ 610}}} calories

{{{A[6]/A[14]=610/x}}}

 {{{9pi/49pi=610/x}}}

{{{9/49=610/x}}}

{{{9x=610*49}}}

{{{9x=29890}}}

{{{x=29890/9}}}

{{{x=3321.11}}}->the number of calories in the {{{14}}} inch pizza
 
Then divide by {{{8}}} to get the number of calories in each slice.


{{{3321.11/8=415.14}}}

nearest whole number of calories in each slice{{{ 415}}}
