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
