What size pizza would be equal in area to two 13inch medium pizzas. 

 

So the Area of two medium pizzas= (3.14 x 13^2/4)2 = 40.8 this is what I got. 

 

But I have no idea what would be equal to that

13  inch diameter =   6.5 in radius

 

Area  of two of these pizzas  =   2 * 3.14 * 6.5^2   =   265.33 in ^2

 

So.....we  need  to solve  for    in this

 

265.33  =  3.14 r^2             divide both sides  by 3.14

 

265.33  / 3.14  = r^2

 

84.5   =  r^2               take  the positive root

 

r ≈  9.2

 

So....we  need   a  2 ( 9.2)   =    18.4 in pizza  to have  the same area as two 13 in pzzas
