+409 what should the size of the small pizza (S) be so that the total area of a large pizza is equal to the area of a small pizza plus the area of a medium pizza?
This is what I got but I am still having trouble with it.
with the small pizza, the equation should be
(3.14(9^2) /4.= 14.13.
Medium pizza radius= (S + 3) / 2 so
A = pi [ (S + 3) / 2 ] ^2
Large pizza radius = ( S + 3 + 3) / 2 = (S + 6) / 2 so
A = pi [ ( S + 6) / 2 ] ^2
So with the total area with the large pizza all you do is just put the 9 in to replace the s. So for the large pizza pi [ ( 9+ 6)^2 ]/ 4 = 31.27 The small pizza area plus the medium pizza area A = pi [ (9 + 3)^2 ] / 4=29.77
equal up the
